To run CMD check on MASS you need to set R_NSIZE in the environment.
500k should do. MASS passes here on Solaris, Linux and Windows, if one
is patient enough. I will point out that information is in the on-line
R complements, page 11.
I have just tried nlme on linux and 0.99.0 and example(nlme.formula)
does fail there in CMD check, eventually.
What MASS does not do is make a PDF manual, and that is mainly due to
problems with the definitions of what needs to be escaped in the
.Rd files. A new version will follow once that is resolved
(which may need 1.0.0).

Um, looks like nlsList is not failing gracefully when memory is exhausted,
presumably because restart is in use.
