Looks very interesting. I'll try it out. >> I think talking about data frames is a bit pointless unless we specify >> what is data frame.

But if you want to have columns which hold values with different type they lo longer a matrix and thing become way more interesting. _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
