fftrees_wordstofftrees {FFTrees} | R Documentation |
Convert a verbal description of an FFT into an FFTrees
object
Description
fftrees_wordstofftrees
converts a verbal description
of an FFT (provided as a string of text) into
a tree definition (of an FFTrees
object).
Thus, fftrees_wordstofftrees
provides a simple
natural language parser for FFTs.
fftrees_wordstofftrees
is the complement function to
fftrees_ffttowords
, which converts an abstract tree definition
(of an FFTrees
object) into a verbal description
(i.e., provides natural language output).
To increase robustness, the parsing of fftrees_wordstofftrees
allows for lower- or uppercase spellings (but not typographical variants)
and ignores the else-part of the final sentence (i.e., the part
beginning with "otherwise").
Usage
fftrees_wordstofftrees(x, my.tree)
Arguments
x |
An |
my.tree |
A character string. A verbal description (as a string of text) defining an FFT. |
Value
An FFTrees
object with a new tree definition as described by my.tree
.
