Thank you for the reproducible example, but your description is missing a clear definition of what you want.
For example, if your desired output is result <- c(rep(0,16),2,1,0,3,1,1,0,1,0,0,0,0,0,0,1,3,2,0,0,1,rep(0,10)) then one answer might be as.vector(table(factor(w,levels=z))) --------------------------------------------------------------------------- Jeff Newmiller The ..... .....
