R help - Jan 2009 - Sweave in LATEX

Hello

I have been setting up my computer to run Sweave. I have got the whole thing
working on example files, except that my MikTex returns an "Undefined
Control Sequence" error for \Sexpr and my output file contains verbatim
code
sequences at the apropriate point in the text rather than the R output. The
rest of the output file is fine with tables, R code sequences and figures in
the right place and correctly formatted. I have searched everywhere for
advice on what to do about this, any ideas would be gratefully received.

You need to give more details.  Which version of R are you running?  How 
are you running Sweave?  Are you including \usepackage{Sweave} in your 
Sweave document?  (This is not always necessary, but is usually a good 
idea).

I have solved the problem. It seems that the \Sexpr{} sequence is processed
by R rather than latex. If you use:

Sweave("Sweave-test-1.Rnw", syntax="SweaveSyntaxNoweb")

When processing in R then this is handled in the appropriate way.
