##---- 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 (fit) 
{
    m = ncol(fit$centers)
    n = length(fit$cluster)
    k = nrow(fit$centers)
    D = fit$tot.withinss
    return(D + log(n) * m * k)
  }
