Hi,
Not sure what you want to do, but take a look at ?duplicated, ?unique,
and maybe ?aggregate; it might be what you're looking for.
HTH,

Hello everyone,
I have a data set like this:
head( fish_transect)
ID_TRANSECT ID_PROJECT DE_ZONE DE_LOCALITY DE_SECTOR MES
1 42 MB Tarragona Creixell Control I 9
2 42 MB Tarragona Creixell Control I 9
3 42 MB Tarragona Creixell Control I 9
4 42 MB Tarragona Creixell Control I 9
5 42 MB Tarragona Creixell Control I 9
6 42 MB Tarragona Creixell Control I 9
ID_SPECIES WEIGHT SIZE N FAMILIA
1 Spondyliosoma cantharus 15.64 10 1 Sparidae
2 Symphodus melanocercus 11.21 10 1 Labridae
3 Diplodus vulgaris 30.20 10 2 Sparidae
4 Diplodus vulgaris 52.24 12 2 Sparidae
5 Diplodus sargus 221.41 14 5 Sparidae
6 Diplodus annularis 3.47 6 1 Sparidae
I have been trying to duplicate the rows where N> 1, that is I want a row
for each animal. Right now as you can see I have for example 5 D. sargus
which are 14 cm length and so on. How can I get 1 row for each animal? I've
been trying the reshape function without success. I also tried in access but
couldn't do it either.
Thanks a lot,
Lucia
