[R] R: Harmonic Analysis

[stephen sefick]

Do you need time localization, or are you only interested in the
period of the high frequency?  If you do need time localization why
not use a CWT to look at the signal?

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.
