Consult the nlme/scripts, were the non-converging parts are commented out. >From 2.2.0, the R/s engines should be similar, so if you update the examples from the book should run. My mileage varied, however: After installing R 2.2.0 (Windows), I immediately tried to run the ping-pong examples in ch06.R and ch08.R, because I had encountered quite few of these in my own stuff. fm1Quin.nlme works now. Strangely, fm2Pheno.nlme still plays merry-go-round. However, when I changed pnlsTol to 0.1, it worked. The results were close to those published, but not exactly the same. I did not try this in previous versions, maybe it would have worked there too with this modification.
