waveslim (version 1.8.5)

basis: Produce Boolean Vector from Wavelet Basis Names

Description

Produce a vector of zeros and ones from a vector of basis names.

Usage

basis(x, basis.names)

Value

Vector of zeros and ones.

Arguments

x

Output from the discrete wavelet package transfrom (DWPT).

basis.names

Vector of character strings that describe leaves on the DWPT basis tree. See the examples below for appropriate syntax.

Details

None.

dwpt.

Examples

Run this code

data(acvs.andel8)
if (FALSE) {
x <- hosking.sim(1024, acvs.andel8[,2])
x.dwpt <- dwpt(x, "la8", 7)
## Select orthonormal basis from wavelet packet tree
x.basis <- basis(x.dwpt, c("w1.1","w2.1","w3.0","w4.3","w5.4","w6.10",
                           "w7.22","w7.23"))
for(i in 1:length(x.dwpt))
  x.dwpt[[i]] <- x.basis[i] * x.dwpt[[i]]
## Resonstruct original series using selected orthonormal basis
y <- idwpt(x.dwpt, x.basis)
par(mfrow=c(2,1), mar=c(5-1,4,4-1,2))
plot.ts(x, xlab="", ylab="", main="Original Series")
plot.ts(y, xlab="", ylab="", main="Reconstructed Series")
}
