Sheets un-even columns range_speedread incorrect

[HugoGit39]

Hi

I have a large Google Sheets with uneven column lengths.

When I use range_speedread it doesnt read the last columns correct. Why?

See this example:

Google sheets:

https://docs.google.com/spreadsheets/d/1t2JYOCsCvK05Layi3loXFWwCBGXjXNUDMUAi9xudiHg/

test <- range_speedread(as_id("1t2JYOCsCvK05Layi3loXFWwCBGXjXNUDMUAi9xudiHg"), show_col_types = F)

I'm not entirely sure what you mean by "doesnt read the last columns correct".

But I think you're just noticing trickiness of column type guessing in the presence of lots of missing data?

The docs for range_speedread() outline various gotchas of this function and point out that, ultimately, readr::read_csv()) gets used.

You can read about readr's column type guessing here:

https://readr.tidyverse.org/articles/column-types.html

But one solution for this dataset is just to instruct readr to use all the rows to guess column type, instead of the first 1000.

  "1t2JYOCsCvK05Layi3loXFWwCBGXjXNUDMUAi9xudiHg",
