WebWhat you have currently coded, loops over values 1 to 3 by using. for (i in 1:length(fdr.list)){ ... } However, you probably want to use a different form and loop over each value in that vector using something more like: for (fdr in fdr.nums.vector){ ... } This way you have convenient access to the FDR value in each loop via the fdr variable. There are several ways to create a vector on the fly. Here are a few options: 1) With a loop (but see for the next solution, as you should try to avoid loops in R): ns <- c (10, 20, 40, 80, 160) ni <- numeric (length (ns)) # pre-allocate the resulting vector for (i in 1:length (ns)) { ni [i] <- round (rnorm (1, mean = ns [i], sd = 1)) } Web4.1 For Loops.
