Here is the data I'm working with: http://r.789695.n4.nabble.com/file/n4530888/new.txt new.txt
http://r.789695.n4.nabble.com/file/n4530888/old.txt old.txt My code is here: http://pastebin.com/9jjs6Ahr I'm looking for away to simply attach the new.txt to the bottom of old.txt through R, else I'll just throw it in Excel to do some preprocessing. I've looked into using merge, cbind, concatenate, and rbind. However, I'm running into problems where the 2012 data keeps ending up on top before the 2010 and 2011 data or the function just adds more extra columns to the right side. Is there a simple method of doing this? Thanks. -- View this message in context: http://r.789695.n4.nabble.com/Trying-to-merge-new-data-set-to-bottom-of-old-data-set-Both-are-zoo-objects-tp4530888p4530888.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.
