using wavelet transform to calculate mean frequency of a signal
global wavelet spectrum? There is something somewhere - I just can't remember where off the top of my head. Stephen Sefick

Dear list,
in short: I would like to calculate the mean frequency
of a signal (e.g. time series) using the wavelet transform.
with details: I did not find a R function to calculate a
mean frequency using one of the cran packages.
My searches using ?R Site Search returned:
**(1)waveclock {waveclock} ? ?R Documentation
Reconstruction of the modal frequencies in a time series using continuous
wavelet transformation and the "crazy climbers" algorithm
(this look like what I wanted to do, but I can't figure it out)
**(2) tfmean {Rwave} ? ?R Documentation
Average frequency by frequency
(this seems not to help either)
I am a bit desperate at the moment
and would very, very much appreciate any help.
Regards,
Stephan
