1. I could find no references to "var.ran" with RSiteSearch("var.ran") and when requesting "var.ran" from S-Plus 6.2.
2. Have you considered "simulate.lme"? 3. Are you familiar with Pinheiro and Bates (2000) Mixed-Effects Models in S and S-Plus (Springer)? I highly recommend this book. spencer graves Mahmoud Torabi wrote: > Dear Sir/Madam > > I would be pleased if anybody can help me.
