summary.FFTrees summarizes key contents of an FFTrees object.
# S3 method for FFTrees
summary(object, tree = NULL, ...)An FFTrees object.
The tree to summarize (as an integer, but may be a vector).
If tree = NULL (as per default) or exceeding the possible range 1:object$trees$n,
information on all trees in object is returned.
Additional arguments (currently ignored).
An invisible list with elements containing the definitions and performance stats
of the FFT(s) specified by tree(s).
Given an FFTrees object x,
summary.FFTrees selects key parameters from x$params
and provides the definitions and performance statistics for tree from x$trees.
Inspect and query x for additional details.
summary.FFTrees returns an invisible list containing two elements:
definitions and corresponding performance measures of trees;
stats on decision frequencies, derived probabilities, and costs (separated by train and test).
A header prints descriptive information of the FFTrees object (to the console):
Its main title, number of trees (object$trees$n), and the name of the criterion variable (object$criterion_name).
Per default, information on all available trees is shown and returned.
Specifying tree filters the output list elements for the corresponding tree(s).
When only a single tree is specified, the printed header includes a verbal description of
the corresponding tree.
While summary.FFTrees provides key details about the specified tree(s),
the individual decisions (stored in object$trees$decisions) are not shown or returned.
print.FFTrees for printing FFTs;
plot.FFTrees for plotting FFTs;
inwords for obtaining a verbal description of FFTs;
FFTrees for creating FFTs from and applying them to data.
