get_fft | R Documentation |
A simple wrapper around mvfft
to perform
Discrete Fourier Transformation, discard redundant components
(for real numbers only, the second half of the transform),
and name columns by 'DC' (direct current, a term from electrical
engineering) and the numbers of cycles in the data set reflected
by each component. The last column is the Nyquist frequency.
