I am currently starting some research on human behavior modeling and prediction. While searching for the best statistics and data mining software I came across a very big $$ issue :) As I am doing this in the course of my PhD and currently the institute/university is not capable of providing a license for it, I decided to go for R.
I am particularly enthusiastic as it can be plugged together with Java and therefore address stuff in real-time. Based on your expertise, do you think this software will limit my results? What you be the major drawbacks of R?
