R help - May 2011 - R-code in R-file documentation

Hello List,
I would like to insert code from .r files into a LaTeX appendix 
(possibly using Sweave).
I was considering:

<<results=tex,eval=true,echo=true>>source("file.r")
@
but I would just like to echo the code and not evaluate the code within 
the file.
maybe:
<<results=tex,eval=true,echo=false>>cat("\\begin{verbatim}")
readLines("file.r")
cat("\\end{verbatim}")
@

The above works well other than the line numbers which are included 
(which isn't so bad).

Thanks for the help and ideas!
Brian

  Wouldn't it be easier to use the LaTeX listings package?

I guess what you want is cat(readLines("file.r"), sep =
"\n")
