Read an FFT definition from tree definitions

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

ffts_df

A set of FFT definitions (as a data frame, usually from an FFTrees object, with suitable variable names to pass verify_ffts_df.

tree

The ID of the to-be-selected FFT (as an integer), corresponding to a tree in ffts_df. Default: tree = 1.

Value

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