These functions are generally not user-facing but used internally
in e.g. the *_equivalence()
functions.
They are documented here.
k_strict(hc, .data)
k_elbow(hc, .data, census, range)
k_silhouette(hc, .data, range)
hc |
A hierarchical clustering object. |
.data |
An object of a
|
census |
A motif census object. |
range |
An integer indicating the maximum number of options to consider. The minimum of this and the number of nodes in the network is used. |
k_strict()
: Selects a number of clusters in which there is no
distance between cluster members.
k_elbow()
: Selects a number of clusters in which there is
a fair trade-off between parsimony and fit according to the elbow method.
k_silhouette()
: Selects a number of clusters that
optimises the silhouette score.
