[R] Merging dataframes

Hi, May I please ask how I do the following in R. Sorry - this may be trivial, but I am struggling here for this. For two dataframes (A and B), I wish to identify (based on a primary key-column present in both A & B) - 1. Which records (rows) of A did not match with B, and 2. Which records

b = 2:11, Sample_1c = 3:12, Sample_2a=4:13, Sample_2b=7:16, row.names=LETTERS[1:10]) groups <- rep (0:1, c(3,2)) kruskal <- apply(myFile [1:nrow(myFile),], 1, kruskal.test, **) p_kruskal <- sapply(kruskal, function(x) x$p.value) Thanks, Chintanu [[alternative HTM

Thank you for your assistance - Arun, Milan, Rui. Much appreciated. In a related note, I have never been sure of how and when to use the binary operator, %in%. If you could share any easy explanation to it, that would be very useful. Cheers, Chintanu === On
