Do you use R for data manipulation?
+1. I worked with Matthew for a while and saw in practice just how powerful that package is. I'm surprised it isn't more widely used. Martin

Another tool I find useful is Matthew Dowle's data.table package. It has very fast indexing, can have much lower memory requirements than a data frame, and has some built-in data manipulation capability. Especially with a 64-bit OS, you can use this to keep things in memory where you otherwise would have to use a database. See here: http://article.gmane.org/gmane.comp.lang.r.packages/282 - Tom
