R is very powerful, but its use is mostly limited to statisticians. So providing a simple interface for people to leverage predictive models built in R is a great idea.<p>But their sample output (<a href="http://predict.i2pi.com/8MjSV2AA" rel="nofollow">http://predict.i2pi.com/8MjSV2AA</a>) just shows the distributions of all the input variables. I don't actually see any predictions.<p>Edit: There are no predictions there because there are no "NA"'s in the sample file to predict. You would think they'd create a demo file that would showcase the predictions!
