Re: [R] Interaction of a dynamic number of factors

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, Dimitris Nigel Birney wrote: Hi, I have a dynamic table structure consis

[R] Interaction of a dynamic number of factors

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 cas
