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

Hi,
I have little experience using wavelet and I would like to know if it is
possible,using R wavelet package, to have a plot of frequency versus time.
thank you
