Know that if I have List_1 and List_2 that I can check to see if the intersect via the code below:
List _1: a, b, c, d, e, f, g List_2: z, y, x, w, v, u, b length(intersect(List_1, List_2)) > 0 return = true If instead I wanted to check a dataframe that is a "list of lists," how would I do that by record without looping? List _1: a, b, c, d, e, f, g List_2: z, y, x, w, v, u, b y, z, w, v, v, u, m z, y, x, a, b, c . . . return true false true , , , -- View this message in context: http://r.789695.n4.nabble.com/Intersecting-list-vs-rows-in-matrix-tp2320427p2320427.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.
