R help - Jul 2008 - Complex to polar?

I am using fft(x) to compute the fft of a real-valued sequence. This returns (as
expected an array of complex numbers. Is ther an R function to transform these
complex numbers into two arrays for the magnitude and phase? Basically polar
notation?

Thank you.

Kevin

Please read ?complex.
