As of the current release (3.5), all functions in bnlearn require
complete data so that error message is expected. However, you can
estimate the CPTs from incomplete data using table() and prop.table()
and assemble them in a fitted BN with custom.fit(). On the other hand,
maybe it would be better to write an EM wrapper around bn.fit() to
make the best of the dependence structure of the data?

Cheers,
    Marco
