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.
