[R] function question

[Felipe Carrillo]

Hi everyone:
I did this before with R and I can't remember how.
I got some fish forklength values
FL  number
34    4
35    3
36    7

I need to breakdown the FL by the number of fish with the same length
like this:
34  1
34  1
34  1
34  1
35  1
35  1
35  1
36  1
36  1
36  1
36  1
36  1
36  1
36  1
