clusters_cor-methods: Compute distance matrix between dendrograms partitions.

In ViSEAGO: ViSEAGO: a Bioconductor package for clustering biological functions using Gene Ontology and semantic similarity

Description

Build a distance or correlation matrix between partitions from dendrograms.

Usage

clusters_cor(clusters, method = "adjusted.rand")

## S4 method for signature 'list,character'
clusters_cor(clusters, method = "adjusted.rand")

Arguments

clusters	a list of GO_clusters-class objects, from GOterms_heatmap or GOclusters_heatmap, named as character.
method	available methods ("vi", "nmi", "split.join", "rand", or "adjusted.rand") from igraph package compare function.

Value

a distance or a correlation matrix.
