Characteristics for a spatial histogram
parameterEstimates(H, breaks)trivariate (output) histogram, estimated by unfold
breaks vector from setbreaks
list of the following entries: either major or minor semi-axis length a,
(polar) angle Theta and shape factor s, see parameters3d
Based on the estimated joint distribution after unfolding the function replicates
the entries of the vector breaks, see setbreaks, equal to the
number of estimated count data for each class. For an example please see the file 'unfold.R'.
