Dear R-help members,

To whom it may concern, our research group is conducting a study to evaluate the predictive  
value of 24 hour blood pressure variability.
We are looking for an R routine that performs a fast Fourier transform spectral analysis
(with an output of the approximation function of the Fourier and estimates the validity
of the model for the various harmonics).
Thanks
Vittorio Colagrande
