Hi,
I often used Sweave in the last few years, but today I could not

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.
For now, I can keep working by placing a copy of Sweave.sty in the
directory where both my ".Rnw" and ".tex" files reside.

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
