We often use Gnu R to work on different things and to solve various exercises. It’s always a disgusting job to export e.g. a matrix with probabilities to a document to send it to our supervisors, but Rumpel just gave me a little hint.

The trick is called xtable and it can be found in the deb repository:

1 | aptitude install r-cran-xtable |

It’s an add on for R and does right that what I need:

It is not only limited to matrices and doesn’t only export to latex, but for further information take a look at `?xtable`

😉

Btw. I just noticed that the GeSHi acronym for Gnu R syntax highlighting is `rsplus`
