[R-pkg-devel] GitHub Action failed re-building 'sos.Rnw'

[Duncan Murdoch]

This page

https://bookdown.org/yihui/rmarkdown-cookbook/install-latex-pkgs.html

suggests that executing this in R should fix the tikz issue:

tinytex::parse_install(
   text = "! LaTeX Error: File `tikz.sty' not found."
)

The "ks" message looks like a missing R package rather than a missing 
LaTeX package, so running install.packages("ks") would fix it.

So the only question is how to do these things in a Github action.  I 
don't know if there's a pre-made recipe for this, but this one should do it:

       - name: Install tikz.tex and ks
         run: |
           install.packages(c('tinytex', 'ks')) # Maybe tinytex is 
already there?
           tinytex::parse_install(
              text = "! LaTeX Error: File `tikz.sty' not found."
           )
         shell: Rscript {0}
