Data Mashups in R

Strung

I've been looking at some stock and forex analysis programs and they all seem sort of eh. I thought to myself, why don't I just apply my Lua knowledge and make models from scratch? But a bit of research has suggested to me that the R programming language is the master of modeling.

Since we have a lot of programmers here, I'm wondering if anyone has any insight into R? I'm thinking about making my own modeling scripts that compare various data points.
