RStudio Question: I am trying to use a loop to populate a matrix of NA values. I know it isn't the best way to do this but this is the method I must use. Below is what I have so far but I am not sure what to put in the loop. For simplicity, I just want a list from 1 to 20.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

n = 20; M = matrix(NA, ncol = 2, nrow = 10);

for (i in 1:n){ # store seq(1, 20) into matrix <--- help here } M

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The goal is to produce the same matrix as this code:

data <- seq(1, 20) M = matrix(data, ncol =2, nrow = 10) M
