If I have a vector of site abbreviations and a vector of depths in those water bodies, is there a simple way in R to combine them to make a third vector? Examples: site depth desired MU 0 MU0 MU 1 MU1 MU 2 MU2 MC 0 MC0 MC 1 MC1 MC 2 MC2 The dataset has many more lines than this. I can see how to do this with lots of if statements, but does R have magic that can make it happen easily? I guess this would be called concatenation. ______________________________________________ R-help at r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
