Harmonic Analysis

My thoughts exactly.

?FFT should do the job.

And define the dominant term - a_n**2 + b_n**2 - the Parseval Relation.

I am looking for a package to perform harmonic analysis with the goal

estimating the period of the
dominant high frequency component in some mono-channel signals.

You should widen your scope by looking a "time series" instead of

harmonic

analysis. There is a task view on the subject at

http://cran.at.r-project.org/web/views/TimeSeries.html

... or take a look at package tuneR.

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
