  statistics = "m", ...)

Value

The result from gseg2, with the constructed graph and realized k added.

Arguments

x

Optional data matrix with observations in rows.

dissimilarity

Optional square dissimilarity matrix or a dist object. Supply exactly one of x and dissimilarity.

k

Number of complete MST layers. The default is floor(sqrt(N)); the largest allowed value is floor(N/2).
