Update on above. I sampled my data to create a 10,000 observation data set.
I then tried lme with a correlation = corSpher and only one predictor, as a
test. I set my memory.limit to the max allowable. It ran for a while then
returned
Error: cannot allocate vector of size 64.0 Mb.
I can see how 50K obs busted it. But 64 Mb? Perhaps there is another limit
set by the lme function? -seth
