Calculate Hill numbers (effective number of observations) for rows or columns

Effective numbers of observations. order=0 produces count of non-zero weights. order=1 produces exp(entropy). order=2 produces the inverse Simpson index.

weitrix_hill(weitrix, what = c("row", "col"), order = 2)

Arguments

weitrix	A weitrix object.
what	Calculate for rows ("row") (default) or columns ("col")?
order	Order of the Hill numbers.

Value

A numeric vector of effective numbers of observations.
