At a glance, I don't see any glaring speed-related flaws. Honestly, I'm curious to see what the R version of the Compute looks like. Others might advise on the use of iterators... > w(i, t) = ped(i, t+3) - pa(i, t); This brings up a question that I've been meaning to ask the list -- Last time I checked, with NumericVectors using myvec[i] was significantly faster than myvec(i) (due to bound and NA checking?). Now that I think of it, I seem to remember discussion of disabling these checks with NumericMatrix et al. Of course, no checking is just another way to shoot my own foot -- I'm a big fan of myvec(i) in day-to-day use :) best, -xian -- A man, a plan, a cat, a ham, a yak, a yam, a hat, a canal – Panama! _______________________________________________ Rcpp-devel mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
