tch <- cbind(threshold, bins, tp, fp) ctch[1:20, ] Thanks again for your help. Cheers, Lyndon On Tue, Jul 12, 2011 at 5:09 AM, Eik Vettorazzi wrote: > Hi, > > Am 11.07.2011 22:57, schrieb Lyndon Estes: >> ctch[ctch$threshold == 3.5, ] >> # [1] threshold val       tp

every single loop, but this is a >>> constant, so it is wasting time. Anyway, you get away even without >>> calculating this once, using >>> >>> tp[i]<-sum(x2>bins[i]) #indexing is not necessary, >>>                        #and 1-x2[j]<=tr == x2[j]>tr &g
