That was not a very helpful reply to someone who asked a question. He could
be counting the rows by asking for the length of a full variable in that
data frame, and not be aware of nrow(x). And one could know about nrow()
without knowing about its page in the manual..
There is no need to jump all over someone who asks a question--some people
are just starting out.
