Error when Trying to use Rticles to generate example R markdown: pdflatex not found Ubuntu 20.04

Question

I was trying to generate one of the example rticles outputs in pdf, and got the same error pdflatex not found. This was on Ubuntu 20.04 focal fossa.

Answer 1

I first followed Yihue's troubleshooting site, but got the same error found here, here, and here . In R on Ubuntu 20.04, I first installed tinytex using devtools::install_github('yihui/tinytex'). I then tried to do library(tinytex) and tinytex::tlmgr_update() which returned an error Error in system2("tlmgr", args, ...) : error in running command. I assumed this was because I was missing something on Ubuntu 20.04. It seems that as of July 14, 2020, Ubuntu 20.04 or rticles does not ship with Texlive, which is necessary for output. I thus ran sudo apt install texlive-full at the command line and was able to run the example.
