Baseline removal using Wavelets package

General
1

Hello.

I wish to perform a baseline removal (high pass filtering) of a time series using 'wavelets' package. I was thinking of using dwt command, zeroing the scaling coefficients manually and then performing the inversion with idwt.

Is there any smarter way of doing this?

If not, how can I zero the dwt S4 slot corresponding to the scaling coefficients?

Regards.

Paulo
