I try to understand the hierarchical randomization as applied in the GRTS design. I randomized 16 points on a square grid, see R script below. The argument do.sample was set to FALSE, so that the result consists of a dataframe of all 16 points instead of a GRTS sample. When plotting the order of the points it appears that the numbers 1-4 are not always in different subsquares (of which there are four) , for instance points 1 and 3 are both in the lower-right subsquare. What am I doing wrong?
