I have a matrix of lists. Something along the lists of (but much bigger than):
x = array(dim=c(2, 2), data=list()) x[1,1] = list(1:5) x[2,1] = list(6:9) x[1,2] = list(10:13) x[2,2] = list(14:16) Each list contains a number of observations/ground truth for a particular state. That is, state <1,1> has observations <1,2,3,4,5>. States may have a different number of observations (which is why I'm not using an array). I have another numeric matrix with the same dimensions and I want to check if its values occur. Something along the lines of: y = array(dim=c(2, 2), data=c(1, 10, 11, 20)) I want to do: y %in% x But it doesn't work as hoped. (I expect: c(T, F, T, F).) I realize that I can do this with sapply, but I was hoping for a faster / smarter solution. Any ideas? Thanks! :) Neal ______________________________________________ R-help@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.
