plotDFT | R Documentation |
Plots the components of a Discrete Fourier Transform (DFT)
as polar coordinates (Re and Im of the complex numbers in the DFT).
Arguments dft
and col
can be segmenTier timeseries
and clustering objects.
plotDFT(dft, col, cycles = 3, radius = 0.9, lambda = 1, bc = "component", ...)
dft |

the number of cycles (index of non-DC DFT component) to be plotted |
radius |
radius of the polar plot circle as a fraction of data to be contained within the radius (smaller amplitude) |
lambda |
parameter for Box-Cox transformation of DFT data; has no
effect for |
