[R] wavethrash

2006-12-12 Thread Vladan Arsenijevic
Hi all! Changing boundary conditions (bc) from "periodic" to "symmetric" in wd (discrete wavelet transform function) results in increasing of number of wavelet coefficients. I have a set of 1024 points (i.e. 10 resolution levels), so instead of 1023 (like in "periodic" case) wavelet coefficients I

[R] wavelet basis

2006-03-28 Thread Vladan Arsenijevic
Dear R-list, I have difficulties to extract the wavelet basis (which I want to integrate). After performing discrete wavelet transform using certain filter, we have the lists of scaling and wavelet coefficients. Is there a simple way to reconstruct the whole basis (or basis vectors per level)? Che
