Dear List,
I have Multi-level Data

and I want to count the frequency of var1 and var2 on the group

I found a way, but there must be a much simpler way.
data.ml -
well, I'm not completely sure I understand what you want to compute
but you may try the following:
data.ml - data.frame(i = 1:8, g = factor(c(1,1,1,2,2,3,3,3)),
var1 = c(3,3,3,4,4,4,4,4), var2 = c(8,8,8,2,2,4,4,4))
data.ml[!duplicated(data.ml$g), -1]
