Hi Ivan,

Thanks for your reply. This is what I want to do:

Imagine my dataset looks like this:

Species	N      Size
Coris julis	1	8
Coris julis	3	10
D.vulgaris	2	12

I have 1 C.julis of 8 cm, 3 C. julis of 10 cm and 2 D.vulgaris of 12 cm. I
want 1 row for each animal, something like this:

Species	N	Size
Coris julis	1	8
Coris julis	1	10
Coris julis	1	10
Coris julis	1	10
D.vulgaris	1	12
D.vulgaris	1	12

I hope that helps. I tried reshape but couldn't do it and from what I've
seen I don't think that aggregate, unique or duplicated would do it... but
I'm not good with R so I can be wrong.

Cheers!

Lucia
