[R] lme() doesn't converge on IGF example

Running the Chapter 4 examples in Pinheiro Bates' Mixed-Effects Models in S and S-PLUS (2000), I get a message that the default optimizer doesn't converge, but using optim for the optimizer results in convergence: library(nlme) fm1IGF.lis - lmList(IGF) fm1IGF.lme - lme(fm1IGF.lis)
