Time-Frequency Plane Position
DESCRIPTION:
Compute the positions of an atom or a crystal on the time-frequency plane.

These functions are generic (see Methods); method functions can be written to handle specific classes of data. Classes which already have methods for these functions include:

cp.atom, cp.crystal, wp.atom, wp.crystal.

USAGE: 
center(x)
bandwidth(x)
freq.center(x)
freq.bandwidth(x)
REQUIRED ARGUMENTS:
x:
any S-PLUS object.
VALUE:
if x is an object of cp.atom or wp.atom, returns a real number; if x is an object of cp.crystal or wp.crystal, returns a vector of the same length.
DETAILS:
See the printed help file for the definitions of cp.atom and wp.atom.

For cp.crystal and wp.crystal, definitions to the atoms are applied to each of the atoms.
