R & gams
At office I have been introduced by another company to new, complex energy

in dealing with huge, hevy-weight linear and non-linear modelling (see an
example in http://www.gams.com/modtype/index.htm) and they say it is almost
the only option for doing it.

How I can debug this error to understand which file or another thing is

Fourier Analysis Help
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
