R tutorial
Dear all, I have just found a 'good' tutorial R for datamining.

rowSums, rowMean and rowCumSums?
...ums for each row of a matrix? My implementation of rowCumSums is rowCumSums <- function(x) t(mapply(function(row)cumsum(x[row,]), 1:NROW(x))) I'm sure it can be improved to have other arguments like na.rm or dims. Is there any hope to have this function in R? Christophe -- Christophe Dutang Ph.D. student at ISFA, Lyon, France website: http://dutangc.free.fr [[alternative HTML version deleted]]

on the optim function
...the R optim function does not return the number of iterations. I still wonder why line 632-634 of optim C, the iter variable is not returned (for the BFGS method for example) ? Is there any trick to compute the iteration number with function call number? Kind regards Christophe -- Christophe Dutang Ph.D. student at ISFA, Lyon, France website: http://dutangc.free.fr
