Problem Sweaving vignettes: MiKTeX's texi2dvi reports errors

Hi, Prof. Ripley,

Yes, indeed, that was my problem - thank you! I made the mistake of
installing in the default path of C:\Program Files\R. I just now reinstalled
in C:\R, and everything worked fine. However, if anyone else runs into this,
you cannot just go off and run texi2dvi on an existing .tex file after
installing in a non-space path: you should rerun the whole Sweave example,
which forces a number of additional required items to be downloaded. Let
that process complete, then rerun again. It works fine! The finished pdf
file sure looks sweet.

Thank you again!

Regards,
= Peter

I get

texi2dvi("Sweave-test-1.tex", pdf=TRUE, quiet=FALSE)

This is pdfeTeX, Version 3.141592-1.20a-rc7.2-2.2 (MiKTeX 2.4) output format

LaTeX Warning: You have requested package
`d:/R/svn/trunk/share/texmf/Sweave',
               but the package provides `Sweave'.

so my guess is that this a path problem with your MiKTeX and it is not
finding Sweave.sty.

Simple questions: where did you install R?  Is there a space in the path?

Hi,

I am trying to create a Bioconductor package. Everything installs and
checks fine. Now I'm on my last step, which is to create a vignette.
I'm trying to test the Sweave process, to make sure I can build a
vignette. I am stuck at the texi2dvi stage, which fails when I try to
process the example Sweave-test-1.tex file.

I am using Windows binary R distributions, and have the same problem
on both the latest developer version (2.2.0 Beta) and the latest
patched version
(2.1.1) . For the Tex processing, I first tried downloading and
installing fpTex, but found that it doesn't have texi2dvi. Some
Googling informed me that recent MiKTeX versions now have that
function, so I just downloaded that (the small installation). Indeed
there is a texi2dvi. The first time I ran it, it downloaded a class file

it needed, so now it at least executes.

However, when I try to run it on the test Sweave tex file, I get an error.
Here's the sequence in R:

library(tools)
example(Sweave)

[...output suppressed]

texi2dvi("Sweave-test-1.tex", pdf=TRUE, quiet=FALSE)

Error in texi2dvi("Sweave-test-1.tex", pdf=TRUE, quiet = FALSE) :

[A command window pops up, and the following is from that window: ]

-----------------
I have also tried running texi2dvi directly on the command line, and
get the same result. I've looked at the manual on the MiKTeX site, but
find nothing that tells me what may be wrong. The Sweave test file
looks fine to me. I have also tried running texify --pdf on the same
file on the command line, but get the same results exactly.

I also went to the R-tools site, and went through their page on MiKTeX
issues. Using their second suggestion (since I'm using the recent
MiKTeX version, which defaults to e-TeX mode), I tried changing the
mode for texinfo from e-TeX Extended to e-TeX Compatibility mode: no
change in results. (I'm assuming that texi2dvi is part of texinfo
package - please correct me if I'm wrong.) [I also tried changing
texinfo from e-TeX to TeX mode, and rebuilt/reloade/refreshed, but
this did not seem to take: texi2dvi still reports that it's in e-TeX
mode.]

Finally, I did try posting this to the bioc-devel list, and got some
good suggestions (which I've tried, results above). They then
suggested I move the question over here.

Regards, and thanks,
