[R] conditional assignment

Hi all I want to conditionally operate on certain elements of a matrix, let me explain it with a simple vector example z- c(1, 2, 3) zz - c(0,0,0) null - (z 2) ( zz - z) zz [1] 1 2 3 why zz is not (0, 0, 3) ? the null - assignment is to keep the console silent in the other hand,
