Are you familiar with Pinheiro and Bates (2000) Mixed-Effects Models in S and S-Plus (Springer)? This book describes how to fit this type of model using 'lme'. I highly recommend this book for anyone interested in this type of problem.
     Hope this helps,

I would like to know how to fit a random effects model to equally spaced time series data. The data is multivariate normal data, I have 11,000 subjects each with 72 monthly observations spanning 6 years. I have 3 fixed effects and 1 random effect, these effects are the same for all 72 observations (i.e. the same model for each response). I'm would like to know how to fit such a model in S-Plus? Also, I'm interested in finding out the correlations between the fixed effects and the random effect? I would be very grateful for your suggestions. Regards,
Martyn
