Hi
I know this is a basic question and I know I have done it before but I
can't find the answer any more.
I have a data set, say:
F1, F2, Value
F1 and F2 are Factors.
I would like to plot
plot(TheCombinationOf(F1, F2), Value)
I remember there was a function for TheCombinationOf() but I

Hello,
I want to be able to create a design matrix with two factors. For instance, if
I have:
t1 - factor(c(1,1,2,2));
t2 - factor(c(1,2,1,2));
design - model.matrix(~ -1 + (t1+t2));
design;
t11 t12 t22
1 1 0 0
2 1 0 1
3 0 1 0
4 0 1 1
But the design matrix I want
