I am using R 2.5 on a Linux Redhat platform. I can successfully run some example *.Rnw files through Sweave and generate pdf files. When I try my own example file, "test.Rnw":

\documentclass[a4paper]{article}
\title{Test Sweave Example}

\author{Thomas Adams}
\begin{document}
\maketitle

In this example we embed parts of the examples from the
\texttt{boxplot} and \texttt{lattice} figures into a \LaTeX{} document
<<>>=
library(verification)
library(lattice)
dat<-read.table("verification_summary_20051024_table.txt",sep="\t",header=TRUE)
\begin{center}

<<fig=TRUE,echo=FALSE>>=
boxplot(dat$MAE ~ dat$BASINID)
abline(h=1)
abline(h=0.5,col="red")
@
\end{center}
\end{document}

I get the following error:

xt4-tir:adams> echo 'Sweave("test.Rnw")' | R --vanilla --quiet  > Sweave("test.Rnw")
Writing to file test.tex
Processing code chunks ...
 1 : echo term verbatim

Error: chunk 1
Error in parse(file, n, text, prompt, srcfile, encoding) :

        syntax error, unexpected $undefined in: "
"
Execution halted

I really do not know where to begin to decipher the error messages. Any suggestions?

Regards,
Tom
