It actually does work, but I think the problem is with your matrix
indexing. 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
}
