\keyword{manip}{compress.imwd}
\begin{Description}\relax
Compress a (thresholded) \code{imwd} class object by removing zeroes.
\end{Description}
\begin{Usage}
\begin{verbatim}
compress.imwd(imwd, verbose=FALSE, ...) 
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{imwd}] Object to compress. Compression only does anything on \code{thresholded} \code{\LinkA{imwd.object}{imwd.object}}. 
\item[\code{verbose}] If this is true then report on compression activity.
\item[\code{...}] any other arguments
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
Thresholded \code{\LinkA{imwd}{imwd}} objects are usually very large and contain many zero elements. This function compresses these objects into smaller \code{\LinkA{imwd}{imwd}} objects by using the \code{\LinkA{compress.default}{compress.default}} function which removing the zeroes. This function is a method for the generic function \code{\LinkA{compress}{compress}} for class \code{\LinkA{imwd}{imwd}} objects. It can be invoked by calling \code{\LinkA{compress}{compress}} for an object of the appropriate class, or directly by calling \code{\LinkA{compress.imwd}{compress.imwd}} regardless of the class of the object
\end{Details}
\begin{Value}
An object of type "\code{imwdc}" representing the compressed imwd object.
