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.
