\HeaderA{threshold}{Threshold coefficients}{threshold}
\keyword{manip}{threshold}
\begin{Description}\relax
Modify coefficients by thresholding or shrinkage. 

This function is generic. 

Particular methods exist for the following objects: 

\item[wd object] the \code{\LinkA{threshold.wd}{threshold.wd}} function is used;
\item[imwd object] the \code{\LinkA{threshold.imwd}{threshold.imwd}} function is used;
\item[imwdc object] the \code{\LinkA{threshold.imwdc}{threshold.imwdc}} function is used;
\item[irregwd object] the \code{\LinkA{threshold.irregwd}{threshold.irregwd}} function is used;
\item[wd3D object] the \code{\LinkA{threshold.wd3D}{threshold.wd3D}} function is used; 
\item[wp object] the \code{\LinkA{threshold.wp}{threshold.wp}} function is used;
\item[wst object] the \code{\LinkA{threshold.wst}{threshold.wst}} function is used.
\end{Description}
