Examples

##---- Should be DIRECTLY executable !! ----
##-- ==>  Define data, use random,
##--	or do  help(data=index)  for the standard data sets.

## The function is currently defined as
function (m = NULL) 
{
    if (is.null(m)) {
        return(list(entropy = NA))
    }
    r_dens = raster(m/sum(m))
    m = values(r_dens) * cellStats(r_dens, function(x, ...) {
        na.omit(log(x))
    })
    m[is.na(m)] = 0
    return(list(entropy = -1/log(ncell(r_dens)) * sum(m)))
  }
