I'm not certain what you want, but it sounds like the answer might be
in '?nlme' help page. Toward the end, it describes the 'Value'
returned
as follows:
an object of class 'nlme' representing the nonlinear mixed-effects
model fit. Generic functions such as 'print', 'plot' and
'summary'
have methods to show the results of the fit. See 'nlmeObject' for
the components of the fit. The functions 'resid', 'coef',
'fitted', 'fixed.effects', and 'random.effects'
can be used to
extract some of its components.
Also, 'str' might help you find what you want.

help
you write a question so it is easier for others to understand, thereby
increasing the chances for a quick and useful reply.
