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 -- View this message in context: http://r.789695.n4.nabble.com/reshape-data-adding-rows-to-dataframe-tp3253640p3253640.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
