\HeaderA{getpacket}{Get a packet of coefficients from a wavelet object}{getpacket}
\keyword{manip}{getpacket}
\begin{Description}\relax
This generic function extracts packets of coefficients from various types of wavelet objects. 

This function is generic. 

Particular methods exist. For objects of class: 

\item[wp] use the \code{\LinkA{getpacket.wp}{getpacket.wp}} method. 
\item[wst] use the \code{\LinkA{getpacket.wst}{getpacket.wst}} method. 
\item[wpst] use the \code{\LinkA{getpacket.wpst}{getpacket.wpst}} method.

See individual method help pages for operation and examples. 

Use the \code{\LinkA{accessC}{accessC}} and \code{\LinkA{accessD}{accessD}} function to extract whole resolution levels of coefficients simultaneously.
