[Tex/LaTex] how to colorize syntax using R + Sweave

beamerlistingssweave

I'm writing a LaTeX document using Sweave (a Beamer presentation, really), which weaves R code and LaTeX. Is there a way to make my chunks of code and its output highlighted? I could use listings package but that would mean I would have to rummage through the .tex file and wrap all Schunks so I'm looking for perhaps more elegant solutions if currently available.

The SweaveListingUtils package contains additions to Sweave that enables pretty-printing input and output using the LaTeX listings package. Example usage can be found in the vignette.

Another alternative is to override the Schunk, Sinput and Soutput environments using \renewenvironment so that they do whatever you want them to.

[Tex/LaTex] Workflow in Sweave: Handling TeX errors

I also use sweave (a few months) and latex (20 years). With a reasonably fast machine, the optimal scheme is simply to rebuild often. I use "make" (on a unix-like machine) so that only the chapters whose Rnw file has changed get rebuilt into tex files. That saves a lot of sweave time.

Alternatively, you can edit the .tex file and work away at errors, and put your results back into the .Rnw file when you're ready. But that's error-prone.

If you run sweave-latex often, and fix errors as soon as you see them, then you won't make so many errors.

The other advice is to use a decent editor (e.g. emacs) that does a lot of the work for you, e.g. finishing off parenthetic blocks, begin/end environments and so forth. That prevents 2/3 of the errors you're likely to make.

[Tex/LaTex] Size of Sweave Output

You can use the \scalebox{} command that comes with the graphicx package. E.g., with

\scalebox{0.7}{%
\begin{tabular}{...}
...
\end{tabular}}

your text will be printed at 70%.

This will only work if you use a Sweave chunk to create an external file (say, tab1.tex) and then include it in the LATEX file using an \include or \input statement, not by printing it directly into you master file with results=tex.

Update:

Given my comment and your updated question, I would suggest to look at the Design package which offers convenient LaTeX export of nice-looking Tables, see summary.formula(). Again, the idea would be to write a Table generated this way into a TeX file, and then \input it into your master Rnw file. You can look at Statistical Reporting, Linking S Output with Report Documents, Literate Programming, Managing Analyses, and Documenting Programs and Data for more detailed illustrations.
