plot.dwt: Plot Discrete Wavelet Transform

In wv: Wavelet Variance

Plot Discrete Wavelet Transform

Description

Plots results of the dwt list in which additional parameters can be specified

Usage

## S3 method for class 'dwt'
plot(x, index = NULL, couleur = NULL, ...)

Arguments

x	A dwt object.
index	A vector containing the indices to scales to be included in the graph. By default index = 1:(min(c(J,4))), where J denotes the number of scales in y.
couleur	A vector of colors of the same size as index used for the different scales depicted in the graph. If couleur contains a single value the the same color will be used for all scales.
...	additional arguments affecting the plot produced.

Examples

# Simulate a Gaussian white noise
n = 10^3
Xt = rnorm(n)

# dwt
Yt = dwt(Xt)

# Graph examples
plot(Yt)
plot(Yt, index = c(1,4,5,6,8,2))
plot(Yt, index = c(1,4,5,6), couleur = "blue")
plot(Yt, index = c(1,4,5,6), couleur = rep(c("blue","yellow"),2))
