[R-sig-phylo] Some questions about PGLS analysis in 'caper' in R

[Long, X.]

Hi,

I meet with some problem when I run PGLS analysis in 'caper' package.

First, I am doing the analysis with multiple trees (100 trees), I repeat
PGLS 100 times with the 100 trees. However, it always takes a long time to
get the result. For each variable, it usually takes 20 hours. Do you have
any suggestion to speed up?

Second, when I ran the analysis for 100 times with 100 trees, it showed:

Problem with optim:52ERROR: ABNORMAL_TERMINATION_IN_LNSRCH.

But if I just run one tree, there is no problem at all. Have you ever been
met with such problem before? How did you deal with it?

Thanks a lot in advance.

All the best,

Xiaoyan
