See the sample below. You could also check out ?seq, ?rep, and ?apply for solving this problem with fewer lines of code. n.max <- 300 NUM <- 25 n.sim <- 10 j <- (n.max/NUM)*n.sim results <- matrix(0, nrow=j, ncol=2) while(NUM <= n.max){ for(i in 1:n.sim){ k <- (NUM/25)*i results[((NUM / 25) - 1) * n.sim + i, 1] <- k results[((NUM / 25) - 1) * n.sim + i, 2] <- NUM cat("Iteration", i, ": NUM=", NUM, "k=", k, "\n") } NUM <- NUM + 25 } This email message, including any attachments, is for the so...{{dropped}} ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
