match() will return an NA, if it cannot find a match, in which case you could use the argument: use="pairwise.complete.obs") in cor() to have it only use pairs with complete data. > Eg: > Ranking X: > A > B > C > Ranking Y: > A > D > C In this example, you would get a correlation of 1, because B from x does not match anything in y, and D from y does not match x, so you're left with A and C which are in the same positions. > > -- > David Nemer -- Joshua Wiley Senior in Psychology University of California, Riverside http://www.joshuawiley.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.
