drop_nodes deletes
one or more nodes from an existing FFT definition
(by removing the corresponding rows from the FFT definition
in the tidy data frame format).
When dropping the final node, the last remaining node becomes the new final node (i.e., gains a second exit).
Duplicates in nodes are dropped only once
(rather than incrementally) and nodes not in
the range 1:nrow(fft) are ignored.
Dropping all nodes yields an error.
drop_nodes is the inverse function of select_nodes.
Inserting new nodes is possible by add_nodes.
drop_nodes(fft, nodes = NA, quiet = FALSE)One FFT definition (as a data frame in tidy format, with one row per node).
One FFT definition (as a data frame in tidy format, with one row per node).
The FFT nodes to drop (as an integer vector).
Default: nodes = NA.
