[R] help on wavelet

[stephen sefick]

It depends on what you want to do.  In wavelet speak frequency is scale.
these are the libraries:
wmtsa - wavCWT (make sure that you pick the wavelet.  I suggest morlet
because it is compactly supported (disappears to zero quickly))
I would also suggest the fields packages for the tim.colors function
which produces the familiar red to blue color scheme.
sowas- more complex stuff here take a look very interesting if you are
trying to tell if two signals are coherent.

hope this helps

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.
