Hi everyone, I'm posting again, since I haven't got an answer (yet :( ). According to R help, manova does not support the inclusion of the Error() term in the formula call. I have repeated measures data for two dependent variables, so this means I can't account for subject variance in time?. Any lights? Thanks in advance, Rodrigo Abt, Department of Economic Studies, SII, Chile.

You might find additional documentation on the ADE4 website: http://pbil.univ-lyon1.fr/ADE-4/ADE-4.html Otherwise, I think you will have to use a specialized software such as MLwiN (http://multilevel.ioe.ac.uk/index.html) which can fit multivariate and multilevel models.

One useful way of looking at she S language, which R implements, is as a complete programming language with some very powerful operators already available. Why not think about putting those operators together to do the computations that you need to do in this case? It's not like starting from scratch in bog Fortran. I suspect this doesn't help much if you don't know enough about the computations you need to do, though. Perhaps there is a hidden message if that is the case. End of sermon.
