By the looks of it, a separate module would be more reasonable since
it would not add a new dependency, as not everyone needs this type of
analysis.
Also, it would not mess with the established r.series...

Hi all,
A friend of mine asked me if it would be possible to do a Fourier
analysis on a raster time series with Grass (or any other tool). Since
I'm no expert in Fourier or time series the first thing that came to
my mind was to send the grass rasters to R and do the processing
there. But then I

I mean) to apply the fourier analysis in a raster time series? Has
anyone done this?
Daniel,
If I understood right, well,
It is possible/ correct to apply fourier
