This function provides various ways to threshold a imwdc class object.
Usage
# S3 method for imwdc
threshold(imwdc, verbose=FALSE, ...)
Value
An object of class imwdc if the compression option is supplied and set to TRUE, otherwise a imwd object is returned. In either case the returned object contains the thresholded coefficients. Note that if the return.threshold option is set to TRUE then the threshold values will be returned rather than the thresholded object.
Arguments
imwdc
The two-dimensional compressed wavelet decomposition object that you wish to threshold.
verbose
if TRUE then the function prints out informative messages as it progresses.
...
other arguments passed to the threshold.imwd function to control the thresholding characteristics such as policy, type of thresholding etc.

Details
This function performs exactly the same function as threshold.imwd except is accepts objects of class imwdc rather than imwd. Indeed, this function physically calls the threshold.imwd function after using the uncompress function to convert the input imwdc object into a imwd object.
