Multiple libraries exist for R to move data around, change the names of entire columns, change values in every single row with regular expressions, drop any values that have no assigned value, it's the swiss army knife of data. There are also all sorts of things you can do with data in R, from mapping with GPS coordinates to complex scientific graphing with ggplot2 and others.
