flip_exits: Flip exits in an FFT definition

In FFTrees: Generate, Visualise, and Evaluate Fast-and-Frugal Decision Trees

Flip exits in an FFT definition

Description

flip_exits reverses the exits of one or more nodes from an existing FFT definition (in the tidy data frame format).

flip_exits alters the value(s) of the non-final exits specified in nodes (from 0 to 1, or from 1 to 0). By contrast, exits of final nodes remain unchanged.

Duplicates in nodes are flipped only once (rather than repeatedly) and nodes not in the range 1:nrow(fft) are ignored.

flip_exits is a more specialized function than edit_nodes.

Usage

flip_exits(fft, nodes = NA, quiet = FALSE)

Arguments

fft	One FFT definition (as a data frame in tidy format, with one row per node).
nodes	The FFT nodes whose exits are to be flipped (as an integer vector). Default: nodes = NA.
quiet	Hide feedback messages (as logical)? Default: quiet = FALSE.

Value

One FFT definition (as a data frame in tidy format, with one row per node).
