Raison d’être

“What is to be sought in designs for the display of information is the clear portrayal of complexity. Not the complication of the simple; rather … the revelation of the complex.”

Edward R. Tufte

ggstatsplot is an extension of ggplot2 package for creating graphics with details from statistical tests included in the information-rich plots themselves. In a typical exploratory data analysis workflow, data visualization and statistical modeling are two different phases: visualization informs modeling, and modeling in its turn can suggest a different visualization method, and so on and so forth. The central idea of ggstatsplot is simple: combine these two phases into one in the form of graphics with statistical details, which makes data exploration simpler and faster.

Summary of available plots

It, therefore, produces a limited kinds of plots for the supported analyses:

Function	Plot	Description
`ggbetweenstats`	violin plots	for comparisons between groups/conditions
`ggwithinstats`	violin plots	for comparisons within groups/conditions
`gghistostats`	histograms	for distribution about numeric variable
`ggdotplotstats`	dot plots/charts	for distribution about labeled numeric variable
`ggscatterstats`	scatterplots	for correlation between two variables

Installation

To get the latest, stable CRAN release:

install.packages("ggstatsplot")

Note:

Linux users may encounter some installation problems, as several R packages require external libraries on the system, especially for PMCMRplus package. The following README file briefly describes the installation procedure: https://CRAN.R-project.org/package=PMCMRplus/readme/README.html

You can get the development version of the package from GitHub.

If you are in hurry and want to reduce the time of installation, prefer-

# needed package to download from GitHub repo
install.packages("remotes")

# downloading the package from GitHub (needs `remotes` package to be installed)
remotes::install_github(
  repo = "IndrajeetPatil/ggstatsplot", # package path on GitHub
  dependencies = FALSE, # assumes you have already installed needed packages
  quick = TRUE # skips docs, demos, and vignettes
)

If time is not a constraint-

remotes::install_github(
  repo = "IndrajeetPatil/ggstatsplot", # package path on GitHub
  dependencies = TRUE, # installs packages which ggstatsplot depends on
  upgrade_dependencies = TRUE # updates any out of date dependencies
)

Note: If you are reading this on GitHub repository, the documentation below is for the development version of the package. So you may see some features available here that are not currently present in the stable version of this package on CRAN. For documentation relevant for the CRAN version, see: https://CRAN.R-project.org/package=ggstatsplot/readme/README.html

`ggbetweenstats`

This function creates either a violin plot, a box plot, or a mix of two for between-group or between-condition comparisons with results from statistical tests in the subtitle. The simplest function call looks like this-

# for reproducibility
set.seed(123)
library(ggstatsplot)

# plot
ggbetweenstats(
  data = iris,
  x = Species,
  y = Sepal.Length,
  title = "Distribution of sepal length across Iris species"
)

📝 Defaults return

✅ raw data + distributions
✅ descriptive statistics
✅ inferential statistics
✅ effect size + CIs
✅ pairwise comparisons
✅ Bayesian hypothesis-testing
✅ Bayesian estimation

A number of other arguments can be specified to make this plot even more informative or change some of the default options.

# for reproducibility
set.seed(123)
library(ggplot2)

# plot
ggbetweenstats(
  data = ToothGrowth,
  x = supp,
  y = len,
  type = "r", # robust statistics
  k = 3, # number of decimal places for statistical results
  xlab = "Supplement type", # label for the x-axis variable
  ylab = "Tooth length", # label for the y-axis variable
  title = "The Effect of Vitamin C on Tooth Growth", # title text for the plot
  ggtheme = ggthemes::theme_fivethirtyeight(), # choosing a different theme
  ggstatsplot.layer = FALSE, # turn off `ggstatsplot` theme layer
  package = "wesanderson", # package from which color palette is to be taken
  palette = "Darjeeling1" # choosing a different color palette
)

Additionally, there is also a grouped_ variant of this function that makes it easy to repeat the same operation across a single grouping variable:

# for reproducibility
set.seed(123)

# plot
grouped_ggbetweenstats(
  data = dplyr::filter(
    .data = movies_long,
    genre %in% c("Action", "Action Comedy", "Action Drama", "Comedy")
  ),
  x = mpaa,
  y = length,
  grouping.var = genre, # grouping variable
  outlier.tagging = TRUE, # whether outliers need to be tagged
  outlier.label = title, # variable to be used for tagging outliers
  outlier.coef = 2,
  ggsignif.args = list(textsize = 4, tip_length = 0.01),
  p.adjust.method = "bonferroni", # method for adjusting p-values for multiple comparisons
  # adding new components to `ggstatsplot` default
  ggplot.component = list(ggplot2::scale_y_continuous(sec.axis = ggplot2::dup_axis())),
  caption = substitute(paste(italic("Source"), ": IMDb (Internet Movie Database)")),
  palette = "default_jama",
  package = "ggsci",
  plotgrid.args = list(nrow = 2),
  annotation.args = list(title = "Differences in movie length by mpaa ratings for different genres")
)

Note here that the function can be used to tag outliers!

`ggwithinstats`

ggbetweenstats function has an identical twin function ggwithinstats for repeated measures designs that behaves in the same fashion with a few minor tweaks introduced to properly visualize the repeated measures design. As can be seen from an example below, the only difference between the plot structure is that now the group means are connected by paths to highlight the fact that these data are paired with each other.

# for reproducibility and data
set.seed(123)
library(WRS2) # for data
library(afex) # to run anova

# plot
ggwithinstats(
  data = WineTasting,
  x = Wine,
  y = Taste,
  title = "Wine tasting",
  caption = "Data source: `WRS2` R package",
  ggtheme = ggthemes::theme_fivethirtyeight(),
  ggstatsplot.layer = FALSE
)

📝 Defaults return

✅ raw data + distributions
✅ descriptive statistics
✅ inferential statistics
✅ effect size + CIs
✅ pairwise comparisons

Robust	trimmed mean	`parameters::describe_distribution`
Bayesian	MAP estimate	`parameters::describe_distribution`

As with the ggbetweenstats, this function also has a grouped_ variant that makes repeating the same analysis across a single grouping variable quicker. We will see an example with only repeated measurements-

# common setup
set.seed(123)

# plot
grouped_ggwithinstats(
  data = dplyr::filter(
    .data = bugs_long,
    region %in% c("Europe", "North America"),
    condition %in% c("LDLF", "LDHF")
  ),
  x = condition,
  y = desire,
  type = "np", # non-parametric statistics
  xlab = "Condition",
  ylab = "Desire to kill an artrhopod",
  grouping.var = region,
  outlier.tagging = TRUE,
  outlier.label = education
)

`gghistostats`

To visualize the distribution of a single variable and check if its mean is significantly different from a specified value with a one-sample test, gghistostats can be used.

# for reproducibility
set.seed(123)

# plot
gghistostats(
  data = ggplot2::msleep, # dataframe from which variable is to be taken
  x = awake, # numeric variable whose distribution is of interest
  title = "Amount of time spent awake", # title for the plot
  caption = substitute(paste(italic("Source: "), "Mammalian sleep data set")),
  test.value = 12, # default value is 0
  binwidth = 1, # binwidth value (experiment)
  ggtheme = hrbrthemes::theme_ipsum_tw(), # choosing a different theme
  ggstatsplot.layer = FALSE # turn off ggstatsplot theme layer
)

📝 Defaults return

✅ counts + proportion for bins
✅ descriptive statistics
✅ inferential statistics
✅ effect size + CIs
✅ Bayesian hypothesis-testing
✅ Bayesian estimation

There is also a grouped_ variant of this function that makes it easy to repeat the same operation across a single grouping variable:

# for reproducibility
set.seed(123)

# plot
grouped_gghistostats(
  data = dplyr::filter(
    .data = movies_long,
    genre %in% c("Action", "Action Comedy", "Action Drama", "Comedy")
  ),
  x = budget,
  test.value = 50,
  type = "nonparametric",
  xlab = "Movies budget (in million US$)",
  grouping.var = genre, # grouping variable
  normal.curve = TRUE, # superimpose a normal distribution curve
  normal.curve.args = list(color = "red", size = 1),
  ggtheme = ggthemes::theme_tufte(),
  # modify the defaults from `ggstatsplot` for each plot
  ggplot.component = ggplot2::labs(caption = "Source: IMDB.com"),
  plotgrid.args = list(nrow = 2),
  annotation.args = list(title = "Movies budgets for different genres")
)

Summary of tests

The central tendency measure displayed will depend on the statistics:

Type	Measure	Function used
Parametric	mean	`parameters::describe_distribution`
Non-parametric	median	`parameters::describe_distribution`
Robust	trimmed mean	`parameters::describe_distribution`
Bayesian	MAP estimate	`parameters::describe_distribution`

For more, including information about the variant of this function grouped_gghistostats, see the gghistostats vignette: https://indrajeetpatil.github.io/ggstatsplot/articles/web_only/gghistostats.html

`ggdotplotstats`

This function is similar to gghistostats, but is intended to be used when the numeric variable also has a label.

# for reproducibility
set.seed(123)

# plot
ggdotplotstats(
  data = dplyr::filter(.data = gapminder::gapminder, continent == "Asia"),
  y = country,
  x = lifeExp,
  test.value = 55,
  type = "robust",
  title = "Distribution of life expectancy in Asian continent",
  xlab = "Life expectancy",
  caption = substitute(
    paste(
      italic("Source"),
      ": Gapminder dataset from https://www.gapminder.org/"
    )
  )
)

📝 Defaults return

✅ descriptives (mean + sample size)
✅ inferential statistics
✅ effect size + CIs
✅ Bayesian hypothesis-testing
✅ Bayesian estimation

As with the rest of the functions in this package, there is also a grouped_ variant of this function to facilitate looping the same operation for all levels of a single grouping variable.

# for reproducibility
set.seed(123)

# plot
grouped_ggdotplotstats(
  data = dplyr::filter(.data = ggplot2::mpg, cyl %in% c("4", "6")),
  x = cty,
  y = manufacturer,
  type = "bayes", # Bayesian test
  xlab = "city miles per gallon",
  ylab = "car manufacturer",
  grouping.var = cyl, # grouping variable
  test.value = 15.5,
  point.args = list(color = "red", size = 5, shape = 13),
  annotation.args = list(title = "Fuel economy data")
)

Summary of tests

This is identical to summary of tests for gghistostats.

`ggscatterstats`

This function creates a scatterplot with marginal distributions overlaid on the axes (from ggExtra::ggMarginal) and results from statistical tests in the subtitle:

ggscatterstats(
  data = ggplot2::msleep,
  x = sleep_rem,
  y = awake,
  xlab = "REM sleep (in hours)",
  ylab = "Amount of time spent awake (in hours)",
  title = "Understanding mammalian sleep"
)

📝 Defaults return

✅ raw data + distributions
✅ marginal distributions
✅ inferential statistics
✅ effect size + CIs
✅ Bayesian hypothesis-testing
✅ Bayesian estimation

The available marginal distributions are-

histograms
boxplots
density
violin
densigram (density + histogram)

Number of other arguments can be specified to modify this basic plot-

# for reproducibility
set.seed(123)

# plot
ggscatterstats(
  data = dplyr::filter(.data = movies_long, genre == "Action"),
  x = budget,
  y = rating,
  type = "robust", # type of test that needs to be run
  xlab = "Movie budget (in million/ US$)", # label for x axis
  ylab = "IMDB rating", # label for y axis
  label.var = title, # variable for labeling data points
  label.expression = rating < 5 & budget > 100, # expression that decides which points to label
  title = "Movie budget and IMDB rating (action)", # title text for the plot
  caption = expression(paste(italic("Note"), ": IMDB stands for Internet Movie DataBase")),
  ggtheme = hrbrthemes::theme_ipsum_ps(), # choosing a different theme
  ggstatsplot.layer = FALSE, # turn off `ggstatsplot` theme layer
  marginal.type = "boxplot", # type of marginal distribution to be displayed
  xfill = "pink", # color fill for x-axis marginal distribution
  yfill = "#009E73" # color fill for y-axis marginal distribution
)

Additionally, there is also a grouped_ variant of this function that makes it easy to repeat the same operation across a single grouping variable. Also, note that, as opposed to the other functions, this function does not return a ggplot object and any modification you want to make can be made in advance using ggplot.component argument (available for all functions, but especially useful here):

# for reproducibility
set.seed(123)

# plot
grouped_ggscatterstats(
  data = dplyr::filter(
    .data = movies_long,
    genre %in% c("Action", "Action Comedy", "Action Drama", "Comedy")
  ),
  x = rating,
  y = length,
  grouping.var = genre, # grouping variable
  label.var = title,
  label.expression = length > 200,
  xlab = "IMDB rating",
  ggtheme = ggplot2::theme_grey(),
  ggplot.component = list(
    ggplot2::scale_x_continuous(breaks = seq(2, 9, 1), limits = (c(2, 9)))
  ),
  plotgrid.args = list(nrow = 2),
  annotation.args = list(title = "Relationship between movie length by IMDB ratings for different genres")
)

Summary of tests

Following tests are carried out for each type of analyses. Additionally, the correlation coefficients (and their confidence intervals) are used as effect sizes-

Type	Test	CI?	Function used
Parametric	Pearson’s correlation coefficient	Yes	`correlation::correlation`
Non-parametric	Spearman’s rank correlation coefficient	Yes	`correlation::correlation`
Robust	Winsorized Pearson correlation coefficient	Yes	`correlation::correlation`
Bayesian	Pearson’s correlation coefficient	Yes	`correlation::correlation`

For more, see the ggscatterstats vignette: https://indrajeetpatil.github.io/ggstatsplot/articles/web_only/ggscatterstats.html

`ggcorrmat`

ggcorrmat makes a correlalogram (a matrix of correlation coefficients) with minimal amount of code. Just sticking to the defaults itself produces publication-ready correlation matrices. But, for the sake of exploring the available options, let’s change some of the defaults. For example, multiple aesthetics-related arguments can be modified to change the appearance of the correlation matrix.

# for reproducibility
set.seed(123)

# as a default this function outputs a correlation matrix plot
ggcorrmat(
  data = ggplot2::msleep,
  colors = c("#B2182B", "white", "#4D4D4D"),
  title = "Correlalogram for mammals sleep dataset",
  subtitle = "sleep units: hours; weight units: kilograms"
)

📝 Defaults return

✅ effect size + significance
✅ careful handling of NAs

If there are NAs present in the selected variables, the legend will display minimum, median, and maximum number of pairs used for correlation tests.

There is also a grouped_ variant of this function that makes it easy to repeat the same operation across a single grouping variable:

# for reproducibility
set.seed(123)

# plot
grouped_ggcorrmat(
  data = dplyr::filter(
    .data = movies_long,
    genre %in% c("Action", "Action Comedy", "Action Drama", "Comedy")
  ),
  type = "robust", # correlation method
  colors = c("#cbac43", "white", "#550000"),
  grouping.var = genre, # grouping variable
  matrix.type = "lower" # type of matrix
)

You can also get a dataframe containing all relevant details from the statistical tests:

# setup
set.seed(123)

# dataframe in long format
ggcorrmat(
  data = ggplot2::msleep,
  type = "bayes",
  output = "dataframe"
)

`ggpiestats`

This function creates a pie chart for categorical or nominal variables with results from contingency table analysis (Pearson’s chi-squared test for between-subjects design and McNemar’s chi-squared test for within-subjects design) included in the subtitle of the plot. If only one categorical variable is entered, results from one-sample proportion test (i.e., a chi-squared goodness of fit test) will be displayed as a subtitle.

To study an interaction between two categorical variables:

# for reproducibility
set.seed(123)

# plot
ggpiestats(
  data = mtcars,
  x = am,
  y = cyl,
  title = "Dataset: Motor Trend Car Road Tests", # title for the plot
  legend.title = "Transmission", # title for the legend
  caption = substitute(paste(italic("Source"), ": 1974 Motor Trend US magazine"))
)

📝 Defaults return

✅ descriptives (frequency + %s)
✅ inferential statistics
✅ effect size + CIs
✅ Goodness-of-fit tests
✅ Bayesian hypothesis-testing
✅ Bayesian estimation

In case of repeated measures designs, setting paired = TRUE will produce results from McNemar’s chi-squared test-

# for reproducibility
set.seed(123)

# data
df_paired <-
  data.frame(
    "before" = c("Approve", "Approve", "Disapprove", "Disapprove"),
    "after" = c("Approve", "Disapprove", "Approve", "Disapprove"),
    counts = c(794, 150, 86, 570),
    check.names = FALSE
  )

# plot
ggpiestats(
  data = df_paired,
  x = before,
  y = after,
  counts = counts,
  title = "Survey results before and after the intervention",
  label = "both",
  paired = TRUE, # within-subjects design
  package = "wesanderson",
  palette = "Royal1"
)

Additionally, there is also a grouped_ variant of this function that makes it easy to repeat the same operation across a single grouping variable. Following example is a case where the theoretical question is about proportions for different levels of a single nominal variable:

# for reproducibility
set.seed(123)

# plot
grouped_ggpiestats(
  data = movies_long,
  x = genre,
  grouping.var = mpaa, # grouping variable
  label.repel = TRUE, # repel labels (helpful for overlapping labels)
  package = "ggsci", # package from which color palette is to be taken
  palette = "default_ucscgb", # choosing a different color palette
  annotation.args = list(title = "Composition of MPAA ratings for different genres"),
  plotgrid.args = list(nrow = 2)
)

Summary of tests

Following tests are carried out for each type of analyses-

Type of data	Design	Test	Function used
Unpaired	$n \times p$ contingency table	Pearson’s $\chi^2$ test	`stats::chisq.test`
Paired	$n \times p$ contingency table	McNemar’s $\chi^2$ test	`stats::mcnemar.test`
Frequency	$n \times 1$ contingency table	Goodness of fit ( $\chi^2$ test)	`stats::chisq.test`

Following effect sizes (and confidence intervals/CI) are available for each type of test-

Test	Effect size	CI?	Function used
Pearson’s $\chi^2$ test	Cramer’s	Yes	`effectsize::cramers_v`
McNemar’s test	Cohen’s	Yes	`effectsize::cohens_g`
Goodness of fit	Cramer’s	Yes	`effectsize::cramers_v`

For more, see the ggpiestats vignette: https://indrajeetpatil.github.io/ggstatsplot/articles/web_only/ggpiestats.html

`ggbarstats`

In case you are not a fan of pie charts (for very good reasons), you can alternatively use ggbarstats function which has a similar syntax.

N.B. The p-values from one-sample proportion test are displayed on top of each bar.

# for reproducibility
set.seed(123)
library(ggplot2)

# plot
ggbarstats(
  data = movies_long,
  x = mpaa,
  y = genre,
  title = "MPAA Ratings by Genre",
  xlab = "movie genre",
  legend.title = "MPAA rating",
  ggtheme = hrbrthemes::theme_ipsum_pub(),
  ggplot.component = list(ggplot2::scale_x_discrete(guide = ggplot2::guide_axis(n.dodge = 2))),
  palette = "Set2"
)

📝 Defaults return

✅ descriptives (frequency + %s)
✅ inferential statistics
✅ effect size + CIs
✅ Goodness-of-fit tests
✅ Bayesian hypothesis-testing
✅ Bayesian estimation

And, needless to say, there is also a grouped_ variant of this function-

# setup
set.seed(123)

# smaller dataset
df <-
  dplyr::filter(
    .data = forcats::gss_cat,
    race %in% c("Black", "White"),
    relig %in% c("Protestant", "Catholic", "None"),
    !partyid %in% c("No answer", "Don't know", "Other party")
  )

# plot
grouped_ggbarstats(
  data = df,
  x = relig,
  y = partyid,
  grouping.var = race,
  label = "both",
  xlab = "Party affiliation",
  package = "wesanderson",
  palette = "Darjeeling2",
  ggtheme = ggthemes::theme_tufte(base_size = 12),
  ggstatsplot.layer = FALSE,
  annotation.args = list(title = "Race, religion, and political affiliation"),
  plotgrid.args = list(nrow = 2)
)

Summary of tests

This is identical to the ggpiestats function summary of tests.

`ggcoefstats`

The function ggcoefstats generates dot-and-whisker plots for regression models saved in a tidy data frame. The tidy dataframes are prepared using parameters::model_parameters. Additionally, if available, the model summary indices are also extracted from performance::model_performance.

Although the statistical models displayed in the plot may differ based on the class of models being investigated, there are few aspects of the plot that will be invariant across models:

The dot-whisker plot contains a dot representing the estimate and their confidence intervals (95% is the default). The estimate can either be effect sizes (for tests that depend on the F statistic) or regression coefficients (for tests with t and z statistic), etc. The function will, by default, display a helpful x-axis label that should clear up what estimates are being displayed. The confidence intervals can sometimes be asymmetric if bootstrapping was used.
The caption will always contain diagnostic information, if available, about models that can be useful for model selection: The smaller the Akaike’s Information Criterion (AIC) and the Bayesian Information Criterion (BIC) values, the “better” the model is.
The output of this function will be a ggplot2 object and, thus, it can be further modified (e.g., change themes, etc.) with ggplot2 functions.

# for reproducibility
set.seed(123)

# model
mod <- stats::lm(formula = mpg ~ am * cyl, data = mtcars)

# plot
ggcoefstats(mod)

📝 Defaults return

✅ inferential statistics
✅ estimate + CIs
✅ model summary (AIC

BIC)

This default plot can be further modified to one’s liking with additional arguments (also, let’s use a different model now):

# for reproducibility
set.seed(123)

# model
mod <- MASS::rlm(formula = mpg ~ am * cyl, data = mtcars)

# plot
ggcoefstats(
  x = mod,
  point.args = list(color = "red", size = 3, shape = 15),
  vline.args = list(size = 1, color = "#CC79A7", linetype = "dotdash"),
  title = "Car performance predicted by transmission & cylinder count",
  subtitle = "Source: 1974 Motor Trend US magazine",
  exclude.intercept = TRUE,
  ggtheme = hrbrthemes::theme_ipsum_ps(),
  ggstatsplot.layer = FALSE
) + # note the order in which the labels are entered
  ggplot2::scale_y_discrete(labels = c("transmission", "cylinders", "interaction")) +
  ggplot2::labs(x = "regression coefficient", y = NULL)

Although not shown here, this function can also be used to carry out parametric, robust, and Bayesian random-effects meta-analysis.

Summary of meta-analysis tests

Type	Test	Effect size	95% CI available?	Function used
Parametric	Meta-analysis via random-effects models	$\beta$	Yes	`metafor::metafor`
Robust	Meta-analysis via robust random-effects models	$\beta$	Yes	`metaplus::metaplus`
Bayes	Meta-analysis via Bayesian random-effects models	$\beta$	Yes	`metaBMA::meta_random`

For a more exhaustive account of this function, see the associated vignette- https://indrajeetpatil.github.io/ggstatsplot/articles/web_only/ggcoefstats.html

`combine_plots`

The full power of ggstatsplot can be leveraged with a functional programming package like purrr that replaces for loops with code that is both more succinct and easier to read and, therefore, purrr should be preferrred 😻.

In such cases, ggstatsplot contains a helper function combine_plots to combine multiple plots, which can be useful for combining a list of plots produced with purrr. This is a wrapper around patchwork::wrap_plots and lets you combine multiple plots and add a combination of title, caption, and annotation texts with suitable defaults.

For examples (both with plyr and purrr), see the associated vignette- https://indrajeetpatil.github.io/ggstatsplot/articles/web_only/combine_plots.html

Using `ggstatsplot` statistical details with custom plots

Sometimes you may not like the default plots produced by ggstatsplot. In such cases, you can use other custom plots (from ggplot2 or other plotting packages) and still use ggstatsplot functions to display results from relevant statistical test.

For example, in the following chunk, we will create plot (ridgeplot) using ggridges package and use ggstatsplot function for extracting results.

# loading the needed libraries
set.seed(123)
library(ggridges)
library(ggplot2)
library(ggstatsplot)

# using `ggstatsplot` to get call with statistical results
stats_results <-
  ggbetweenstats(
    data = morley,
    x = Expt,
    y = Speed,
    output = "subtitle"
  )

# using `ggridges` to create plot
ggplot(morley, aes(x = Speed, y = as.factor(Expt), fill = as.factor(Expt))) +
  geom_density_ridges(
    jittered_points = TRUE,
    quantile_lines = TRUE,
    scale = 0.9,
    alpha = 0.7,
    vline_size = 1,
    vline_color = "red",
    point_size = 0.4,
    point_alpha = 1,
    position = position_raincloud(adjust_vlines = TRUE)
  ) + # adding annotations
  labs(
    title = "Michelson-Morley experiments",
    subtitle = stats_results,
    x = "Speed of light",
    y = "Experiment number"
  ) + # remove the legend
  theme(legend.position = "none")

Summary of benefits

No need to use scores of packages for statistical analysis (e.g., one to get stats, one to get effect sizes, another to get Bayes Factors, and yet another to get pairwise comparisons, etc.).
Minimal amount of code needed for all functions (typically only data, x, and y), which minimizes chances of error and makes for tidy scripts.
Conveniently toggle between statistical approaches.
Truly makes your figures worth a thousand words.
No need to copy-paste results to the text editor (MS-Word, e.g.).
Disembodied figures stand on their own and are easy to evaluate for the reader.
More breathing room for theoretical discussion and other text.
No need to worry about updating figures and statistical details separately.

Syntax simplicity

All functions produce publication-ready plots that require very few arguments if one finds the aesthetic and statistical defaults satisfying make the syntax much less cognitively demanding and easy to remember.

Misconceptions about ggstatsplot

This package is…

❌ an alternative to learning ggplot2
✅ (The better you know ggplot2, the more you can modify the defaults to your liking.)

❌ meant to be used in talks/presentations
✅ (Default plots can be too complicated for effectively communicating results in time-constrained presentation settings, e.g. conference talks.)

❌ the only game in town
✅ (GUI software alternatives: JASP and jamovi).

`ggstatsverse`: Components of `ggstatsplot`

To make the maintenance and development of ggstatsplot more manageable, it is being broken into smaller pieces. Currently, the package internally relies on the following packages that manage different aspects of statistical analyses:

`statsExpressions`

The statsExpressions package forms the statistical backend that processes data and creates expressions containing results from statistical tests and are by default displayed in as plot subtitle and caption.

For more exhaustive documentation for this package, see: https://indrajeetpatil.github.io/statsExpressions/

`pairwiseComparisons`

The pairwiseComparisons package forms the pairwise comparison backend for creating results that are used to display post hoc multiple comparisons displayed in ggbetweenstats and ggwithinstats functions.

For more exhaustive documentation for this package, see: https://indrajeetpatil.github.io/pairwiseComparisons/

`ipmisc`

The ipmisc package contains some of the data wrangling/cleaning functions and a few other miscellaneous functions.

For more exhaustive documentation for this package, see: https://indrajeetpatil.github.io/ipmisc/

Extensions

In case you use the GUI software jamovi, you can install a module called jjstatsplot, which is a wrapper around ggstatsplot.

Acknowledgments

I would like to thank all the contributors to ggstatsplot who pointed out bugs or requested features I hadn’t considered. I would especially like to thank other package developers (especially Daniel Lüdecke, Dominique Makowski, Mattan S. Ben-Shachar, Patrick Mair, Salvatore Mangiafico, etc.) who have patiently and diligently answered my relentless number of questions and added feature requests I wanted. I also want to thank Chuck Powell for his initial contributions to the package.

The hexsticker was generously designed by Sarah Otterstetter (Max Planck Institute for Human Development, Berlin). This package has also benefited from the larger rstats community on Twitter and StackOverflow.

Thanks are also due to my postdoc advisers (Mina Cikara and Fiery Cushman at Harvard University; Iyad Rahwan at Max Planck Institute for Human Development) who patiently supported me spending hundreds of hours working on this package rather than what I was paid to do. 😄

Code coverage

As the code stands right now, here is the code coverage for all primary functions involved: https://codecov.io/gh/IndrajeetPatil/ggstatsplot/tree/master/R

Contributing

I’m happy to receive bug reports, suggestions, questions, and (most of all) contributions to fix problems and add features. I personally prefer using the GitHub issues system over trying to reach out to me in other ways (personal e-mail, Twitter, etc.). Pull Requests for contributions are encouraged.

Here are some simple ways in which you can contribute (in the increasing order of commitment):

Read and correct any inconsistencies in the documentation
Raise issues about bugs or wanted features
Review code
Add new functionality (in the form of new plotting functions or helpers for preparing subtitles)

Please note that this project is released with a Contributor Code of Conduct. By participating in this project you agree to abide by its terms.
