This list
contains the following object:
A 554 x 13 matrix
. It contains the extracted fourier parameters (the order 0 harmonic A_0 and the first 6ths hamornics an_i and bn_i) for the 554 characters.
A data.frame
containing the character's annotation. That is with columns
writer
the writer's id (from 1
