[R] nlme and memory

[Bill Simpson]

I am trying to follow an example in Pineiro & Bates's book

library(nlme)
data(Soybean)
soy.lis<-nlsList(weight~SSlogis(Time,Asym,xmid,scal),data=Soybean)
soy.nlme<-nlme(soy.lis)
Error: Calloc could not allocate (151974496 of 8) memory

This is not a large problem-- only 412 observations. I am using R-1.2.3
with automatic memory allocation. Does this message mean that I need to
run this example on a machine with 151 MB of physical RAM available (even
with X, R, etc loaded)? Or maybe I can increase my swap space? Or maybe
this error message is wrong somehow?? This seems like a large memory
requirement for this problem.

Thanks very much for any help.
