\title{Threshold coefficients}
\description{
Modify coefficients by thresholding or shrinkage.
This function is generic.
Particular methods exist for the following objects:
\describe{
\item{wd object}{the \code{\link{threshold.wd}} function is used;}
\item{imwd object}{the \code{\link{threshold.imwd}} function is used;}
\item{imwdc object}{the \code{\link{threshold.imwdc}} function is used;}
\item{irregwd object}{the \code{\link{threshold.irregwd}} function is used;}
\item{wd3D object}{the \code{\link{threshold.wd3D}} function is used;}
\item{wp object}{the \code{\link{threshold.wp}} function is used;}
\item{wst object}{the \code{\link{threshold.wst}} function is used.}
}
}
\usage{
threshold(...)
}
\arguments{
\item{\dots}{See individual help pages for details.}
}
\details{
See individual method help pages for operation and examples.
}
\value{
Usually a copy of the input object but containing thresholded or shrunk coefficients.
