Re: [R] Selecting from matrix and then stacking in array.

I think changing nrow() to NROW() will get around that error. However, this, as you can see, this goes a little astray at the end. Perhaps something like this will work for you: z.ext <- rbind(z,array(0,c(9,3))) z.out <- array(0, c(3,3,9)) for(i in 1:9){ z.out[,,i] <- cbind(z.ext[c(i,i+3,i+6),
