Hello,
I am not expert in wavelet.
i am working with a discrete dataset in 3D. I applied the D4 wavelet
transform to each dimension sequentially. I made some analysis in the
transformed space and i detected some interesting vowel.
My question is. How is it possible to map a 3d coordinate in the transformed
space to the related coordinate in the 3d original dataset? (i think that
probably one (x,y,z point in the 3d transformed space will be related
probably with 8 vowels in the orginal one...))
Thanks in advance for the help

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.
You might also try stackoverflow.com or stackexchange.com
good luck
