Hi, I have to use a loop to perform a quite computer intensive estimation and I would like to know the progress of the loop during the process. I tried to include something like print(paste(k,date(),sep=" : ")) where k is the number of the iteration, but the result appears only at the end of the loop. Can someone help me please ? ___________________________________________________________________________ D?couvrez un nouveau moyen de poser toutes vos questions quelque soit le sujet !

You need to use flush.console() on Windows, as in: dat <- matrix(runif(20), ncol = 2) res <- numeric(length = 10) for(i in 1:10) { res[i] <- sum(dat[i, ]) cat(paste("Iteration #:", i, "-", date(), "\n")) flush.console() } Depending on how you want the printed statements to appear on the screen, you'd be better off with cat not print, e.g.: cat(paste(k,date(),sep=" : ")) If this isn't the solution, post a reply containing information about your R version, OS, and a reproducible example (simple code & data as I did) to show us the problem.
