  "Description": "The 'fftab' package stores Fourier coefficients in a\ntibble and allows their manipulation in various ways. Functions\nare available for converting between complex, rectangular\n('re', 'im'), and polar ('mod', 'arg') representations, as well\nas for extracting components as vectors or matrices. Inputs can\ninclude vectors, time series, and arrays of arbitrary\ndimensions, which are restored to their original form when\ninverting the transform. Since 'fftab' stores Fourier\nfrequencies as columns in the tibble, many standard operations\non spectral data can be easily performed using tidy packages\nlike 'dplyr'.",
