No LOGLM coefficients

Dear R-helpers, Im trying to fit a Log-linear model on a dataset with bird counts from 60 sites over 14 years for 12 months each (factors for the models). One of the aims is to predict the missing values in this dataset with model predictions. Ive first tried to work with GLM's, that worked fine except for models with one or more interaction-terms. The GLMs run, run .. for hours. So I switched to using LOGLM (MASS-library), and that worked swift. The deviances were the same so that worked well. The only problem is that my data contains both zero's (rarely) and quite a lot of NA's. LOGLM doesn't report the params in these cases (the help file reports this) but I still want to use them for predicting my missing values.
What you want is the fitted values, not the coefficients, I think. You can get those, I believe, from loglm/loglin. If not, you know who to bug: the author of loglm is WNV, although I made it work under R.
