accessD


Get "detail" (mother wavelet) coefficients data from wavelet object

DESCRIPTION

This generic function extracts detail from various types of wavelet objects. It extracts and returns a whole resolution level of coefficients. To obtain individual packets from relevant transforms use the getpacket() series of functions.

This function is generic.

Particular methods exist. For objects of class:

wd
use the accessD.wd method.
wd3D
use the accessD.wd3D method.
wp
use the accessD.wp method.
wpst
use the accessD.wpst method.
wst
use the accessD.wst method.

See individual method help pages for operation and examples.

USAGE

accessD(x, level, ...)

REQUIRED ARGUMENTS

x
a wavelet object of some kind.
level
which level of coefficients you wish to extract.

OPTIONAL ARGUMENTS

...
methods may have additional arguments.

VALUE

A vector coefficients representing the detail coefficients for the requested resolution level.
