You could define a list and then just access the appropriate elements of that list: my.f <- function(a, b) { x1 = equation 1 x2 = equation 2 x3 = equation 3 L <- list(x1, x2, x3) y <- L[[a]] + L[[b]] } my.f(1,2) my.f(2,3) -Peter Ehlers Lisa wrote: Dear all, I have a question about

What are you trying to do? Your example is not what is commonly called ANOVA (some call it ANCOVA) and more often lm() is used. I suspect that you intended 'population' to be a factor, and it is not. So population:condition is not an interaction but different slopes for population by levels
