R [1] is an open source tool for doing statistical analysis. It is an reimplementation of S-Plus [2] and uses the scripting language of S-Plus for interaction. The learning curve is therefore typically longer than with a graphical user interface. But R creates professional graphics which can be exported to many formats (pdf, png, etc.). In the case you want to use it, there is a nice alternative GUI written in Java [3] called JGR.
