Compare Fitted Objects
.DN
The columns in `object1' and `object2' are put together in
matrices which allow direct comparison of the individual elements for
each object. Missing columns in either object are replaced by
`NA's.
.CS
compareFits(object1, object2, which)
.RA
.AG object1,object2
data frames, or matrices, with the same
row names, but possibly different column names. These will usually
correspond to coefficients from fitted objects with a grouping
structure (e.g. `lme' and `lmList' objects).
.OA
.AG which
an optional integer or character vector indicating which
columns in `object1' and `object2' are to be used in the
returned object. Defaults to all columns.
.RT
a three-dimensional array, with the third dimension given by the number
of unique column names in either `object1' or `object2'. To
each column name there corresponds a matrix with as many rows as the
rows in `object1' and two columns, corresponding to `object1'
and `object2'. The returned object inherits from class
`compareFits'.
