basis: Produce Boolean Vector from Wavelet Basis Names

In waveslim: Basic Wavelet Routines for One-, Two-, and Three-Dimensional Signal Processing

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)

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.

Value

Vector of zeros and ones.

See Also

dwpt.

Examples

data(acvs.andel8)
## Not run: 
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")

## End(Not run)
