The fun Package: Use R for Fun!

A couple of days ago we released a package named fun to CRAN, but I did not dare to send an announcement to [email protected] as usual. This package is a collection of some classical computer games (e.g. the Mine sweeper and Five in a row) as well as other funny stuff. Some examples: ## install.packages('fun')

Sweave and pgfSweave in LyX 2.0.x (experimental)

May 25, 2011

bout half a year ago, I wrote a post on the configuration of (pgf)Sweave and LyX, which was intended to save us some efforts in going through all the details during the configuration.

Sweave and pgfSweave in LyX 2.0.x (experimental)

Please ignore this post completely, because Sweave support has become mature in LyX since 2.0.2, and I no longer plan to add the pgfSweave module in LyX. For pgfSweave users, you may consider the new knitr module (available since 2.0.3) which uses the ...

Produce Authentic Math Formulas in R Graphics

I remember a few weeks ago, there was a challenge in the R-help list to make the prime symbol in R graphics. In LaTeX, we simply write $X'$ or $X^\prime$.
