[R] Complex demodulation [SEC=UNCLASSIFIED]

[Augusto.Sanabria at ga.gov.au]

I am trying to complex demodulate a time-series data
(eg geomagnetic field time series) at different frequencies.
I wonder whether there is an R package implementing the complex
demodulation method.

Any information about this would be greatly appreciated.

Regards,

Augusto
