As written, this is a wavelet question, not an R one ... it's possible that you will get help, but if you don't it's because you're asking in the wrong place (i.e. on an R-help list). Also, if you do choose to continue asking on R lists, you should ask on r-help (the general help list) rather than here (r-devel, the list for r development). It would increase your chances a lot if you specified what you were doing (at a minimum, which contributed packages you are using -- as far as I know there is know wavelet capability in base R -- and probably which particular functions from those packages). It would be best if you could provide a reproducible question -- although I recognize that could be difficult in this case.
