Unfortunately its complaining that 'by.x' and 'by.y' specify different numbers of columns'.
I don't really see why that matters if your matching tbh... I'm having a few problems. Merge is definitely what I want but my files are way too big and i'm having memory trouble. Plus I figures out the ID column isn't unique but I guess i can just use by.y="anotheridentifyingcolumn" to get around that. -- View this message in context: http://n4.nabble.com/Matching-rows-in-a-Data-set-I-m-Stuck-tp1576432p1576544.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.
