Dear List, I have a data frame called trait with roughly 800 species in, each species have 15 columns of information:
Species 1 2 3 etc.. a t y h b f j u c r y u etc.. I then have another data frame called com with the composition of species in each region, there are 506 different communities: community species NA1102 a NA1102 c NA0402 b NA0402 c AT1302 a AT1302 b etc.. What i want to do is extract the information held in the first data frame for each community and save this as a new data frame. Resulting in : - community_NA1102 a t y h c r y u community_NA0402 b f j u c r y u Thanks in advance for any suggestions / code. ______________________________________________ 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.
