sample.from.vector <- c(rep("std",1760),rep("dev",240))
make.vector <- rep(99,2000)
for (i in 1:2000){ make.vector[i] <- sample(sample.from.vector,1,replace=F) }
As I understand the above code (which is not very well, obviously), each iteration assigns one element from the sample.from.vector to the current make.vector element; the element choosen from sample.from.vector is tagged so that i is not selected again. However, after the loop, make.vector contains, for example, 1758 stds and 242 devs. Each iteration results in a different proportion of stds and devs (although close to the desired, not right on).
Any help would be greatly apprecitated.
