getdata {LS2W}

Extracts detail coefficients from imwd object

Description

This function is called by cddews to extract the detail coefficients from an object of class imwd.

Usage

getdata(imwd, switch, co.type = "sqr", verbose = FALSE)

Arguments

imwd

An object of class imwd.

switch

Dictates whether the extracted information is structured by "direction" or "scale".

co.type

Dictates the coefficient type which is used. For cddews this must be "sqr".
