select_nodes: Select nodes from an FFT definition

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

Select nodes from an FFT definition

Description

select_nodes selects one or more nodes from an existing FFT definition (by filtering the corresponding row(s) from the FFT definition in the tidy data frame format).

When not selecting the final node, the last selected node becomes the new final node (i.e., gains a second exit).

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

select_nodes is the inverse function of drop_nodes.

Usage

select_nodes(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 to select (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).
