| read_fft_df {FFTrees} | R Documentation |
Read an FFT definition from tree definitions
Description
read_fft_df reads and returns
the definition of a single FFT (as a tidy data frame)
from the multi-line FFT definitions of an FFTrees object.
read_fft_df allows reading individual tree definitions
to manipulate them with other tree trimming functions.
write_fft_df provides the inverse functionality.
Usage
read_fft_df(ffts_df, tree = 1)
Arguments

tree |
The ID of the to-be-selected FFT (as an integer),
corresponding to a tree in |
Value
One FFT definition (as a data frame in tidy format, with one row per node).
