Dear All, I am trying to fill in a blank vector ("a") with one value at a time, with the value of the number of rows in a randomized dataset with rowSums=0. Below is the code I've got so far, but what I want to be as the last line is " a[1st NA,]=nz" such that this will run until all of my NAs are replaced with an integer value based on randomizations.
a<-matrix(nrow=1000,ncol=1) while(sum(is.na(a)>0)) { z<-matrix(rbinom(832, 1, prob = 0.048), nrow = 32) rs<-rowSums(z) nz<-length(rs[rs==0]) a[,]=nz } Thank you for your help!
