Hi all, I’m stuck trying to figure out the appropriate way to include figures generated by a README.Rmd for package submission to CRAN. Any advice much appreciated. Here is the problem:
- I generated an RMarkdown package README using `devtools::use_readme_rmd()`, leaving the chunk options intact (i.e. `fig.path=‘README-‘`) - I included basic instructions and links to the vignettes but would also like to include an example figure so I added a chunk in the README.Rmd that generates and correctly saves the resulting figure in README-example-1.png - The package passes `devtools::check(cran = TRUE)` without errors, warnings or notes but generates a warning on win-builder because of the figure with the following message: *Conversion of 'README.md' failed:pandoc.exe: Could not fetch README-example-1.pngREADME-example-1.png: openBinaryFile: does not exist (No such file or directory) * I understand that this is correct behavior because the file is of course explicitly excluded from the build (`^README-.*\.png$` in .Rbuildignore), and without this line in .Rbuildignore I would get a different warning that this png should indeed not be part of the build. What I could not figure out is how I should proceed with this so it passes win_builder. I checked how this is done in the ggplot2 GitHub repository (which also includes a figure in its README.md that is generated by a README.Rmd) and made sure my .Rbuildignore and other settings are all correct. I eventually realized that the README.html generated on CRAN for ggplot2 actually does not have the png included either ( https://cran.r-project.org/web/packages/ggplot2/README.html) so perhaps this is just not possible and I need to communicate to win_builder that it will indeed be missing this png in some way? Or perhaps I should just avoid having an example figure in the README altogether? Any help much appreciated, I apologize if this turns out to be a trivial question and there is some different way I should be generating the README for submission to CRAN.
