On a sub-architecture build such as the CRAN MacOS distribution that will
be R_HOME/etc/<arch>/Renviron, and on that distribution it is defined as
'false'. So you do need to define to a proper value in your environment,
e.g. put R_LATEXCMD=latex in your ~/.Renviron file.
Thanks Brian. Tried that just now --- and of course it didn't work.
(*Nothing* ever works for me! :-( ) In more detail --- I found that
I didn't *have* a .Renviron file. So I created one, with the single
line
R_LATEXCMD=latex
But I got the same error situation as before. Is there any other action
I need to take to get the system to notice my ~/.Renviron file?
Oops, sorry, R CMD does not read ~/.Renviron. You need to set
R_LATEXCMD=latex in the shell you use to run 'R CMD Rd2dvi'.
I checked that
> Sys.getenv("R_LATEXCMD")
now does indeed return "latex".
as R does read ~/.Renviron.
Be that as it may, I tried the expedient of sudo editing the Renviron
file in R_HOME/etc/i386 and changing ``false'' to ``latex'' in the
definition of R_LATEXCMD.
And *that* worked, at least.
It might be worth discussing on R-sig-mac why the default is not 'latex'.
This is what is done on Windows, another system on which a TeX
installation is optional.
I am cc-ing this message to the R-sig-mac list.
cheers,
Rolf
