Hello R-users, I've got a huge table with about 20.00 rows and 50 columns. The table now has headers as Members1, Members2 etc. My data are 8 different individuals. And I've got a column with clusters. So each individual belongs to different clusters and can occurs multiple times within a cluster (that's the reason that there can be more than 8 members). I want a presence/ absence table for each individual within each cluster. So I want to go from: Cluster Member1 Member2 etc. 1 ind1 ind2 2 ind3 ind1 3 ind2 ind1
to cluster ind1 ind2 ind3 1 1 1 0 2 1 0 1 3 1 1 0 Has anybody any idea how I can do this? I already tried alot of things with pivottables (using cast()) But I think I'm missing out on something. thank you -- View this message in context: http://r.789695.n4.nabble.com/pivot-table-help-tp4155144p4155144.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.
