Writing big documents with Sweave. Is it possible to do as with LaTeX?

Question

I am just discovering Sweave and R. I have seen some examples of Sweave documents and have also started to write one or two on my own. I a

Answer 1

Here is what works very well for me:

I have one master file ("master.Rnw") that has no text but only serves to collect the files (chapters, sections) which form the document in the end.

Then I have one file with R code that is being reused in various other files ("func.Rnw"). Here, I have lot of named chunks

<>=
# code:
c <- a * b
@

In master.Rnw, the first thing after \begin{document} I do is

\SweaveInput{func.Rnw}

and from there, I have my named chunks available. In a file "chap1.Rnw" I can now have

<>=
a <- 10
b <- 25
<>
c
@

Of course, I have to

\SweaveInput{chap1.Rnw})

into master.Rnw.

I only have to \Sweave{master.Rnw} and then pdflatex the resulting master.tex file, no copying/ pasting or processing of multiple files.

I'm just writing a paper of 60+ pages with about 25 tables and figures and everything works perfectly well so far.

Hope this helps, Rainer
