Error: --- re-building ‘PlottingGuide.Rnw’ using knitr_notangle
Error: Error: processing vignette 'PlottingGuide.Rnw' failed with diagnostics:
Running 'texi2dvi' on 'PlottingGuide.tex' failed.
Messages:
You don't have a working TeX binary (tex) installed anywhere in
your PATH, and texi2dvi cannot proceed without one.  If you want to use
this script, you'll need to install TeX (if you don't have it) or change
your PATH or TEX environment variable (if you do).  See the --help
output for more details.
For information about obtaining TeX, please see http://tug.org/texlive,
or do a web search for TeX and your operating system or distro.
On Debian you can install a working TeX system with
  apt-get install texlive

Seems like this can be fixed with this action. This comes from the same r-lib ecosystem that our action already uses.
