In shoebodh/radialpsd: Calculates Radially Averaged Power Spectrum (periodograms) of a 2D matrix
Description
This package is based on the methods described by Mugglestone and Rainshaw (1998).
The r-spectra are calculated by averaging the fourier coefficients produced by base R's
fft() after transforming the cartesian coordinates in to polar. Both omni-directional
(i.e. over a circular region defined the distance) and
directinal (averaged over a slice defined by an angle +- offset) can be calculated
