Suppose A is a fixed factor and B is a random factor. A and B are crossed. Another random factor C is nested in B. Taking into account the AB and AC interactions, how should I fit the model using lme function in the nlme package? Thanks.

The tricky part here is to specify the right formula.
For a basic introduction to nlme, I recommend this document.
