I am trying to run the Sweave example at
http://www.stat.uni-muenchen.de/~leisch/Sweave/Sweave-Rnews-2002-3.pdf
However, the \Sexpr{} code is not being evaluated, although the actual R
code within the {} runs ok in R.
Below is part of the resulting .tex file. Can anyone help identify the
cause? I am using R 2.10.1 on Windows XP.
Consider the \texttt{cats} regression example from Venables \& Ripley
(1997). The data frame contains measurements of heart and body weight
of \Sexpr{nrow(cats)} cats (\Sexpr{sum(cats$Sex=="F")} female,
\Sexpr{sum(cats$Sex=="M")} male).
Thanks

I think I have solved the problem. In the Sweave manual it mentions that
problems may occur after loading the R2HTML package. I have not
recently loaded this package but the proposed solution to problems
caused by R2HTML also solves my problem with the evaluation of R code in
\Sexpr. It seems that it is necessary to set the syntax option in the
Sweave function as follows
Sweave(..., syntax="SweaveSyntaxNoweb")
although I am not sure why this is required.

?I had the same problem before and I think it has something to do with the
R2HTML package.
To take care of that problem simply sweave your rnw file like this:
Sweave("yourfile.Rnw",syntax="SweaveSyntaxNoweb")
and try Sexpr{} again.

What other packages do you have loaded? Sometimes things interfere with each other. Also, what version, os, etc are you working with? (the info asked for in the posting guide). -- Gregory (Greg) L.
