rendering Rmd Markup to pdf not working

[shalberd]

What steps did you take and what happened:

• Took a most recent R image and played around with it.
• Created some sample R rmd markup files. Background: https://rmarkdown.rstudio.com/authoring_quick_tour.html
• Tried with knit button to make a PDF (Knit PDF) out of them (render and output as PDF)

What did you expect to happen:
@guimou Expected pdf file to be rendered and created.

Anything else you would like to add:
solved it by installing in the base OS CentOS 9 the following package (in Containerfile / Dockerfile):
From CentOS 9 appstream repo.

RUN yum install -y texlive-framed

After that, the PDF from markup, with Knit on the R Studio UI, was rendered and created correctly in a new popup window, frame, I guess.

Got the hint from

rstudio/rmarkdown#39

Environment:

• OpenDatahub Version: (please check the operator version)
• Workbench: (all, data-science, etc)
• Workbench Version: (2023.1, etc)
• Specific tool: (jupyterlab, rstudio server, code-server, elyra-pipelines,etc)
• Notebook-Controller Version: (please check the image version in notebook-controller deployment)

This is broken in JupyterLab as well,

• [Bug]: Cant download notebook as a PDF #210
• Fix PDF export opendatahub-io-contrib/workbench-images#37

This is broken in JupyterLab as well

interesting, requires e.g. different OS packages, compared to what I list / install here for R Studio. Thank you for the cross-linking here, cool.
Small side note: for jupyterlab, I currently use / build on / extend contrib :-) @jiridanek so I can confirm that if you end up making the changes that Guillome did in contrib # 37 here as well, you will be fine / all set.

Thus, fixing it like @guimou did in workbenches-images jupyter contrib seems a good idea for Jupyterlab.
