| select_nodes {FFTrees} | R Documentation |
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: |
quiet |
Hide feedback messages (as logical)?
Default: |
Value
One FFT definition (as a data frame in tidy format, with one row per node).
