nlme fixed effects specification
dear R experts: sorry, I have to ask this again. I know that the answer is in section 7.2 of "S Programming," but I don't have the book (and I plan to buy the next edition---which I hope will be titled S/R programming ;-) ). I believe the following yields a standard fixed-effects estimation: fixed.effects = as.factor( as.integer( runif(100)*10 ) ) y=rnorm(100); x=rnorm(100);
