Ok this question is not exactly technical but very pertinent and current.
If you may have not heard Eureqa (http://creativemachines.cornell.edu/eureqa) is a machine learning (?) based tool that helps you find hidden equations and mathematical relationships within the data. It does sound futuristic and experimental and to a great degree it seems it is.
This is the relevant talk by Eureqa inventor Hod Lipson

So i believe this can become popular amongst many R users .
On the official site one can obtain Eureqa clients for MATLAB, Mathematica, Python etc but none so far for R.
So this question is just what it is , is anyone of you working on creating one...or if you know this project do you know what it will take to make one ?
