Support of Wavelet/Cosine Packet Funcrion

DESCRIPTION:

Compute the support of a wavelet or cosine packet function.

This function is an S Version 3 generic (see Methods); method functions can be written to handle specific S Version 3 classes of data. Classes which already have methods for this function include:
cosine.packet, cosine.packet.2d, wavelet.packet, wavelet.packet.2d .

USAGE:

support(x) 

REQUIRED ARGUMENTS:

x
an object of class cosine.packet, cosine.packet.2d, wavelet.packet or wavelet.packet.2d.

VALUE:

for 1D objects, returns a vector of length two, representing an interval; for 2D objects, returns a 2 by 2 matrix.
