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).
Then I must be confused. The usual approach of :
methods(summary.lme) ---> summary.lme* (among many others)
getAnywhere(summary.lme)
A single object matching ‘summary.lme’ was found
It was found in the following places
registered S3 method for summary from namespace nlme
namespace:nlme
... seems to work just fine.

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.

Hello,
I have installed the nlme package, but every time I try to use the
function "summary.lme,"
How did you "try to use it"?
I get a message that the function cannot be
found.
If it says it cannot be found, then you quite possibly forgot to
load the
"lme4" package.
(or the nlme package)
Try:
require(nlme)
