image.wst {wavethresh}

Produce image representation of a wst class object

Description

Produces an image representation of the coefficients contained within a wst.object class object.

Usage

## S3 method for class 'wst'
image(x, nv, strut = 10, type = "D", transform = I, ...)

Arguments

x

The wst object you wish to image

nv

An associated node vector, this argument is no longer used and should be omitted (in the S version it permitted coloration of particular bases)

strut

The number of pixels/width that each coefficient should be drawn with

type

Either "C" or "D" depending on whether you wish to image scaling function coefficients or wavelet ones

transform

A numerical transform you wish to apply to the coefficients before imaging
