do you mean something like this:
f1 <- gl(2, 2, length = 15)
f2 <- gl(3, 2, length = 15)
f3 <- gl(4, 2, length = 15)
f4 <- gl(5, 2, length = 15)
fcomb <- interaction(f1, f2, f3)
table(fcomb, f4)
I hope it helps.
Best,

Hi, I have a dynamic table structure consisting of N factors (e.g. columns
Factor_1, Factor_2,..Factor_N).
I want to construct a table that has as rows the level combinations of
factors F_1..F_n-1, and as columns the levels of the factor Fn. The cells of
the table would contain the number of cases that correspond to these level
combinations. How can I do this?
