>I did a ?unix in R and it came back with system() and
>said unix was deprecated so I replaced unix("read stuff") with system("read stuff") but all i get is a warning "read not found" and
>it flies through the successive plots and i can't see them.
>Thanks for any help on this. It's much appreciated.
