[R-SIG-Mac] /usr/local/bin not writable

[Göran Broström]

Simon,

thanks for your advice which I followed and it works (of course). My 
next step was to install pandoc so I could write pdf reports. I did it 
with the aid of homebrew  and got it in /opt/homebrew/bin/, which is in 
my PATH. My Makefile is

R_OPTS=--no-save --no-restore --no-init-file --no-site-file

paper4.pdf: paper4.Rmd
	R ${R_OPTS} -e "rmarkdown::render('paper4.Rmd')"
	pdflatex paper4.tex

and this makes fine. However (and this is my question), running it from 
inside Rapp:

 > rmarkdown::render('paper4.Rmd')

gives me "Error: pandoc version 1.12.3 or higher is required and was not 
found". (My version is 2.17.1.1)

 > system("echo $PATH") indeed shows that /opt/homebrew/bin is missing,

but issuing 'echo $PATH' at the command line gives a much longer PATH 
including /opt/homebrew/bin and ~/Library/TinyTeX/...

Do I have to set PATH in .Renviron? I have set the PATH in .zshrc

Thanks again!

Göran

PS. No such problems on my ubuntu machine.

If you really want to do that (ie. there is no other user on the machine) then you can simply use

Until I tried 'tinytex'. Gave me the message in the Subject line, with a recommendation: "make it writable". I, however, vaguely remember a recommendation about not touching /usr/local/, so what do you recommend?
