I'd like to run sparse PCA on some economic data. There appear to be several R functions available including elasticnet and PMA but I wanted to check if anyone had something coded up directly in MMA they might be willing share?

Thanks, Peter

Did you give RLink a try? Its meant for such purpose where you can mix and use existing R code/library on the fly from your Mathematica code. –  PlatoManiac Jan 25 at 12:32
    
@PlatoManiac Thanks, yes intend to use RLink if no MMA code available. Wanted to check if MMA version available so I might have more control over algo and diagnostics. –  pjc42 Jan 25 at 19:10
