What is the reason?? Thank you, Irina Irina Foss Environmental Research Institute North Highland Coll...

Hello everybody. My name is Angela. I'm doing wavelet using the sowas library. The problem I have is that I don't know how to choose the paremeters to describes differnt wavelet analysis. How I select the noctave, nvoice, w0, s0,...? I hope my question is clear enough. Thank you very much beforehand.

Dear helpers, When I use the function cgt of library Rwave, the time axis of the plot is always on the [0,1] scale regardless of the original time. This happedn when I tried to reproduce some pictures of "Practical Time-Frequency Analysis", e.g. Figure 3.5 and 3.6 using the codes provided in the book. But the figures of the book display the real sampling time using the same codes.
