Hi there, a-data.frame(c(1,2,2,5,9,9),c(A,B,C,D,E,F)) names(a)-c(x1,x2) max(table(a$x1)) [1] 2 The above shows the max count for x1 is 2, which is correct. But we can't tell there are 2 groups that meet this criteria: 2,2 and 9,9. I then want to extract the records that has the

[R] tapply help

Dear R gurus, I am trying perform what I believe will be a pretty simple task, but I'm struggling to figure out how to do it. I have two vectors of the same length, the first is numeric and the second is factor. I understand that tapply is perfect for applying a function to the numeric vector
