Hi,
I often used Sweave in the last few years, but today I could not get it to
work.
What is 'it'? What exactly did you run (in R or elsewhere)?
Sorry for the lack of precision. Sweave worked perfectly within R. It is when
I tried to compile the ".tex" document with LaTeX (via TeXShop) that i got
the error message.
I got this in the LaTeX console:
LaTex error: file 'sweave.sty' not found.
The filename should be Sweave.sty: do you have a case-insensitive file
system? If not, that is the problem: it is looking for the wrong file
name.
I don't know if my system is case-insensitive (Mac OS X 10.5.5), I think it
is. More importantly, I wrote the error message wrong. I just checked and
Sweave was capilalized.
Not finding Sweave.sty is correct if you are running latex directly on the
file in R 2.8.0 (sic, see the posting guide). You are expected to use R
CMD Sweave, or Sweave() inside R. See the NEWS item
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.
which inter alia tells you how to get the old behaviour (and the bugs it
caused). The alternative is to manually add the directory mentioned to
TEXINPUTS.
I should have been clearer that Sweave worked well within R, and that it was
my LaTeX installation could not find Sweave.sty. In fact I hesitated between
asking the Mac-LaTeX list or the Mac-R list, and decided upon the later
because I felt more readers of this list use both R and LaTeX.
I guess my question becomes: why do I get this message from LaTeX that I did
not get when I was using R 2.7 instead of 2.8, TeXLive 2007 instead of 2008.
And I've answered that in the NEWS section I quoted to you and the
following para. It is a deliberate change in R, controlled by
SWEAVE_STYLEPATH_DEFAULT.
For now, I can keep working by placing a copy of Sweave.sty in the directory
where both my ".Rnw" and ".tex" files reside.
Denis
I am not sure when I lost the ability to use Sweave but in the last 4-5
weeks I reinstalled my OS (10.5.5), R (2.8) and LaTeX (from TeXLive 2008
using MacTeX).
In the past I had nothing special to do, Sweave just worked after
Iinstalled LaTeX and R.
I use a MacBook Pro.
Thanks in advance,
Denis
