[R] Sweave and \input or \include LaTeX commands

[Gregor GORJANC]

Hi!

What is wrong if there would be the same command? Recall my example from 
previous posts and at the end of this mail. If I have a file a.Rnw and this
one inputs file a1.Rnw. My idea was that Sweave would check \input{a1} or 
\include{a1} statements. If file a1 would have extension .Rnw it would
parse it otherwise (i.e. having .tex) it would skip it. Sweave would just 
parse .Rnw files, while latex would put all of them in one file during 
typesetting.

Example:
- we have files
   a.Rnw, which has \input{a1} or \include{a1}
   a1.Rnw
- run Sweave(a.Rnw) and you get
   a.tex
   a1.tex
- run LaTeX (i.e. texi2dvi --pdf a.tex) and you get
   a.pdf

Having new command i.e. \SweaveInput{} would also do the job perfectly,
however I don't se any new benefits of it. One should write more or less 
the same R code as for \input or \include.

Friedrich
I agree that it should not be the same command. I have put an
\SweaveInput{} on my 2do list, should be doable for R 2.1.0.

: Imagine this situation:
:
: % --- a.Rnw start ---
: \documentclass{book}
: \usepackage{Sweave}
: \begin{document}
: % some toy example
: <<print=TRUE>>=
: x <- 1:10
:  <at>
: % now we input additional file
: \input{a1}
: % and lets look again at x
: <<print=TRUE>>=
: x
:  <at>
: \end{document}
: % --- a.Rnw end ---
:
: % --- a1.Rnw start ---
: %\usepackage{Sweave}
: % add 1 to x
: <<print=TRUE>>=
: x <- x + 1
:  <at>
: % --- a1.Rnw end ---
