Compress a (thresholded) imwd class object
by removing zeroes.
DESCRIPTION
Compress a (thresholded) imwd class object
by removing zeroes.
USAGE
compress.imwd(imwd, verbose=F)
REQUIRED ARGUMENTS
- imwd
- Object to compress. Compression only does anything on
thresholded imwd
objects.
OPTIONAL ARGUMENTS
- verbose
- If this is true then report on compression activity.
VALUE
An object of type "imwdc" representing the
compressed imwd object.
DETAILS
Thresholded imwd
objects are usually very large and
contain many zero elements. This function compresses these
objects into smaller imwdc
objects by using the
compress.default
function which removing the zeroes. This
function is a method for the generic function
compress
for class imwd objects.
It can be invoked by calling compress for
an object of the appropriate class, or directly by calling
compress.imwd regardless of the class
of the object.
