Compare Fitted Objects
Description
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
NAs.
Usage
compareFits(object1, object2, which)
Arguments
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. |
which |
an optional integer or character vector indicating which
columns in |
Value
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.
