This is exactly the problem: apps launched through the Finder do not
go through the usual shell initialization process, where the PATH is
typically set up. The two solutions would be to either use the full
path to the command, or else start R.app from the Terminal, via the
command:
open -a R
If you start R.app this way, it will get the same path as your shell.

I don't own or use a Mac, but I've seen something like this happen
to people running R through ESS on some Emacs on a Mac.
Apologies for lack of precision here in terminology, but it had
something to do with the PATH getting set through a shell
initialization file (e.g., .cshrc, .bashrc). Thus, starting in a
shell, the path was set properly. But the path was not set in the
'Mac GUI environment', so things started 'from there' (i.e., by
clicking something), did not know about the path.
If it is a situation like the above, it really has nothing to do
with R directly. If that is the problem, there is probably some
way to set environment variables so that the Mac GUI shell knows
about them.

Dear list,
I want to run latex from an R script:
system("latex mysource.tex")
or:
texi2dvi("mysource.tex", pdf = TRUE, clean = FALSE, quiet
= TRUE, texi2dvi = latex)
but latex does not seem to be on the search path:
/bin/sh: line 1: latex: command not found.
Although 'printenv PATH' tells me that the usr/texbin is looked
for executables:
/Library/Frameworks/Python.framework/Versions/Current/bin:/sw/bin:/
sw/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/texbin:/
usr/X11R6/bin Or am I wrong here?
In any case this is strange because if I call latex from the
Terminal shell it runs without problems. On the other hand
texi2dvi from the tools package also does not work (for the same
reason?)
I use R version 2.6.2 on Intel Mac OS X 10.4.11
Why is there a difference between the way the call to latex
behaves directly in the shell or via the R system () command?
Thanks in advance for any advice!
Christoph
