lmeObject
Fitted lme Object
An object returned by the lme
function, inheriting from class
lme
and representing a fitted linear mixedeffects
model. Objects of this class have methods for the generic functions

Value
The following components must be included in a legitimate lme
object.apVar = FALSE
in the list
of control values used in the call to lme
, this
component is equal to NULL
.lme
call that
produced the object.fixed
and
random
, where the first is a vector containing the estimated
fixed effects and the second is a list of matrices with the estimated
random effects for each level of grouping. For each matrix in the
random
list, the columns refer to the random effects and the
rows to the groups.N
 the number of observations in
the data, Q
 the number of grouping levels, qvec

the number of random effects at each level from innermost to
outermost (last two values are equal to zero and correspond to the
fixed effects and the response), ngrps
 the number of groups
at each level from innermost to outermost (last two values are one
and correspond to the fixed effects and the response), and
ncol
 the number of columns in the model matrix for each
level of grouping from innermost to outermost (last two values are
equal to the number of fixed effects and one).X
and terms
specifying the denominator degrees of freedom for, respectively,
ttests for the individual fixed effects and Ftests for the
fixedeffects terms in the models."ML"
for maximum
likelihood, or "REML"
for restricted maximum likelihood.lmeStruct
,
representing a list of mixedeffects model components, such
as reStruct
, corStruct
, and varFunc
objects.
