This (generic) function returns an object of class
These objects represent analysis-of-variance and analysis-of-deviance tables.
When given a single argument it produces a table which
tests whether the model terms are significant.
When given a sequence of objects,
the models against one another in the order specified.
The print method for
anova objects prints tables in a
The comparison between two or more models will only be valid if they
are fitted to the same dataset. This may be a problem if there are
missing values and R's default of
na.action = na.omit is used.
