cosine.packet(taper="poly2", level=0, block=0,interval=c(0, 1), dct.type=2, frequency=0, epsilon=.5)
The algorithms for the taper functions are given in the S+WAVELETS User's Manual, in the section "Cosine Packet Algorithms". They are discussed in greater depth in Wickerhauser (1994).
Generic functions such as print, plot, summary, support have methods to show the properties of the cosine.packet object.
