Thank you.
What do you exactly mean by "Y|A values is adjusted for the B values"?
And Yes. It works! Using the interaction I got what I expected as intercept.
Thanks

Try instead with lm(Y ~ A * B). You should get intercept (1), main
effects(1+2) and
interaction terms(2) which should total the number of groups.
Appropriately combined,
these estimates will now exactly fit the "raw values".
