LaTeX is very strong for typesetting mathematical equations. Fast Tube by Casper Other useful resources are provided on the Supplementary Material page.

I wrote before about using heatmap tables to combine the strengths of tables and graphics for nominal data. Here is a neat approach using Sweave and latex to produce an effect like in the picture. This latex code is self-contained. Just save it as myfile.Rnw, run Sweave(myfile.Rnw) from inside R and then pdflatex myfile.tex

I love the idea of using R+LaTeX+Sweave for reproducible research. This is even easier now that R has a jazzy new IDE that supports Sweave syntax highlighting and automatic PDF generation. I know I'm going to take some flak for saying this, but let's ...
