Print the sourced R file to an appendix using Sweave

Question

I keep R and Rnw files separate, then load the R data/plots with load(\"file.R\") in the first Sweave chunk. Is there a way that I can print the sourced R file

Answer 1

I usually solve this by:

\begin{appendix}

\section{Appendix A}

\subsection{R session information}

<>=

toLatex(sessionInfo())

@


\subsection{The simulation's source code}

<>=

Stangle(file.path("Projectpath","RnwFile.Rnw"))

SourceCode <- readLines(file.path("Projectpath","Codefile.R"))

writeLines(SourceCode)

@
\end{appendix} 

Using this you have to think of a maximum numbers of characters per line.
