what version of Wine are you running? and is this the patched (1.4.1) version
of
WinBUGS that you're trying to run?
cheers,

mike,
try installing directly using apt-get instead of Synaptic.
in my /etc/apt/sources.list i added the line:
deb http://cran.R-project.org/bin/linux/ubuntu/ dapper/
and then i did:
bash$ sudo apt-get install r-base r-doc-info r-doc-pdf r-doc-html
r-mathlib r-base-html
r-b
the transform that i provided orientates the data matrix so that when plotted
with image
or levelplot the result is isomorphic to what you see when you print the matrix
at the r
prompt.
i don't know what your data look like---"commented, minimal, self-contained,
reproducible
code" would help---
rm(list=ls(all=TRUE))
graphics.off()
# make a test matrix:
nr<- 3
nc<- 4
# the data:
( m<- matrix((1:(nr*nc)), nr, nc) )
[,1] [,2] [,3] [,4]
[1,]147 10
[2,]258 11
[3,]36
below is a very simple bash script to run Sweave from a cygwin terminal, run
pdflatex on
the generated .tex file, and then view the resulting .pdf output.
i usually use cygwin when i am (forced to be on) Windoze, but i found a few
issues
with paths that this script works around.
pdfview, used

\end{itemize}
There are, however, advantages to doing things this way:
\begin{itemize}
\item I can save the plot to a file without writing any other code;
\item I can include the saved plot in my \LaTeX\ figure, allowing me to
fine-tune with the [EMAIL PROTECTED]@ command.
\end{itemize}
\end{
the problem is a little hard to explain; the .Rnw files (below)
probably do a better job, but here goes ...
Sweave doesn't like it when i size a graphical device in a code
chunk using either, e.g.:
windows(width=20, height=5)
in Windows, or, e.g.
x11(width=20, height=5)
under X
ndows FAQ 2.8 - works well.
