summary
is a generic function used
to produce result summaries of the results of
various model fitting functions.
The function invokes particular method
s
which depend on the class
of the first argument.
For factor
s, the frequency of the first maxsum - 1
most frequent levels is shown, where the less frequent levels are
summarized in "(Others)"
(resulting in maxsum
frequencies).
The functions summary.lm
and summary.glm
are examples of particular methods which summarise
the results produced by lm
and glm
.
summary
depends on the
class of its argument. See the documentation of the
particular methods for details of what is produced by that method.anova
