It is quite amazing to see how easy and straightforward it has become to integrate C++ and R, with the help from Rcpp (especially with the new "attribute" function) and Rstudio. More information can be found here.

Use github

I am getting started with github. I found this post helpful.

Knitr, Rstudio, and TikZ

I did not realize that this is such a powerful combination until today. It makes it possible to directly work on a Sweave file that has both text and code in the same document quite attractive (as opposed to begin an R program and a LaTeX file, then combine them together in the end).

Do not use GTK 3 theme wit Mate desktop

I am not sure why, but using GTK 3 theme with Mate desktop significantly slows it down.

Extra themes for ggplot2

Ggthemes is a new package that provides additional themes for ggplot2. It can even be used to draw a Stata-like graph. I particularly like the Tufte-style, as outlined in The Visual Display of Quantitative Information.

Mint Debian

I finally got tired of the old Ubuntu 10.04, which has bee sitting in my main computer for over two years. Instead of a more recent version of Ubuntu or Mint, I replaced it with Mint Debian. I then followed the instruction in this post to install the proprietary NVIDIA driver to get the full power of my graphics card. I really like the simple and elegant design of the Mate desktop and hope I don't ever need to re-install system on this machine ever again (because Mint Debian is a rolling distribution).
