Subject: FFT, frequs, magnitudes, phases
Hi,
I'm in dire need of a fast fourier transformation for me stupid biologist,
i.e. I have a heartbeat signal and would like to decompose it into pure sin
waves, getting three vectors, one containing the frequencies of the sin
waves, one the magnitudes and one the phases (that's what I get from my data
acquisition software's FFT function).
I'd be very much obliged, if someone could point out which command would do
the job in R.
Thanks!
Wolfgang
