The function is not exported from the package. You have to get tough with it,
e.g.
> library(nlme)
> summary.lme
Error: object 'summary.lme' not found
But if you insist:
> nlme:::summary.lme
function (object, adjustSigma = TRUE, verbose = FALSE, ...)
{
fixed <- fixef(object)
...
You cannot do this with lme4 since there the methods are S4 rather than S3
(which is why it has a 4 in the name, I suspect, like the stats4 package).
Also, tucked away in the 'ape' package there is a function varcomp() which
extracts variance components from lme objects. This is all I have ever needed
in addition to what is provided in nlme directly.

Thanks for the suggestions - I tried all of them, including
require(lme4) and require(nlme) and summary.lme still cannot be found.
I want to use it to get full output of a multi-level model. Maybe it's
a Mac thing?
Any other suggestions would be much appreciated! Thanks, again.
