question about contrast in R for multi-factor linear regression models?
Hi all,
I am using "lm" to fit some anova factor models with interactions.
The default setting for my unordered factors is "treatment". I
understand the resultant "lm" coefficients for one factors, but when
it comes to the interaction term, I got confused.
