IIRC, I initially created in my ~/bin folder a script Sweave.sh which
is called for the Sweave process. If you have a similar set-up, then a
third option is to change Sweave.sh from
echo "library(utils); Sweave(\"$1\")" | R --no-save --no-restore
echo "library(utils); Sweave(\"$1\", stylepath=TRUE)" | R --no-save --no-restore
By setting stylepath=TRUE in the call to Sweave, the complete
hard-coded path to sweave.sty is put into the .tex file, which makes
the .tex file somewhat less portable.
Charles: if your problem started to arise with 2.8.0, then the reason
is this entry in the NEWS file:
o The default for 'stylepath' in Sweave's (default)
RweaveLatex driver is now FALSE rather than TRUE if
SWEAVE_STYLEPATH_DEFAULT is unset : see ?RweaveLatex.
To support this, tools::texi2dvi adds the R 'texmf' directory
to the input search path.
Kasper: I agree that this is annoying. If I have a .tex file with a
hard-coded path to an sweave.sty file that no longer exists (since a
new version of R was installed and the old removed), then I get an
error message if I try to process again and the problem is easily
fixed. Remembering to always copy the newest version of sweave.sty
into the latex path or changing SWEAVE_STYLEPATH_DEFAULT with each
upgrade of R is very easily forgotten and could, in my opinion, lead to
much more obscure errors that are then harder to diagnose.
