Re: [Rd] strange lme errors (PR#8477)

lme is not part of R, but of the contributed package nlme. So if you thought this is an lme error, you reported it in the wrong place. See the BUGS section in the FAQ.

Try traceback(). It will probably tell you the message comes from nlminb, in which case try ?nlminb. The problem here is the change in lme from optim to nlminb which seems to have broken many examples.

Searching for that message would have lead you to suggestions that it comes from a bug in your compiler. RSiteSearch() lead me to

And googling showed that your OS has gcc 3.4.2 with its broken Fortran compiler. So it seems this is not a bug in lme nor in R but in your OS.

The reference is! More specifically the URL given points you to section 3.
