Hi R-devels,
I encounter the following problem when I want to build a vignette
in the package building process under Windows
platform i386-pc-mingw32
arch i386
os mingw32
system i386, mingw32
status
major 2
minor 7.0
year 2008
month 04
day 22
svn rev 45424
language R
version.string R version 2.7.0 (2008-04-22)
TeX-Distribution: MikTeX 2.7
My R home directory is the default one:
C:\Program Files\R\R-2.7.0,
so R.home() from package tools makes out of it
"C:\\PROGRA~1\\R\\R-27~1.0"
which does not contain spaces, but instead the special
character ~ .
So function texi2dvi() from package tools makes texi2dvi
include the directive
\usepackage{C:\PROGRA~1\R\R-27~1.0\share\texmf\Sweave}
into the corresponding .tex file for the vignette, and, consequently,
MikTeX throws an error (due to the ~'s).
According to
http://developer.r-project.org/blosxom.cgi/R-devel
this is due to a change on Apr 15.
If I am right, the use of short filenames (without spaces)
as to be found in %R_HOME% for
MikTeX (and tetex) would no longer have been necessary:
http://wiki.lyx.org/LaTeX/FilesWithSpecialChars
So an easy way out would be to revert the changes made in
R-2.7.0 and instead use a quoted version of the full path
constructed by normalizePath().
In the mean time, of course one might simply alert people
to have Sweave.sty on their tex filename database / search path
and to include \usepackage{Sweave} in their .Rnw files.
Best,
Peter
