I have been asked how to handle the following situation in R:

Given an unbalanced design of 3 crossed random effects, such as
subject, rater and item, how to estimate the variance components?

I know how to do it using lme, but this seems to be limited to
the nested case; or to use aov with error strata, when the
design is balanced.
