MDSplot-methods: Multi Dimensional Scale (MDS) plot

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

Description

Generate a Multi Dimensional Scale (MDS) plot from distance objects.

Usage

MDSplot(object, type = "GOterms", file = NULL)

## S4 method for signature 'ANY'
MDSplot(object, type = "GOterms", file = NULL)

Arguments

object	a GO_SS-class or GO_clusters-class objects from distances computed with compute_SS_distances.
type	could be "GOterms" to display GOterms MDSplot, or "GOclusters" to display GOclusters MDSplot.
file	static image output file name (default to NULL).

Details

This method build and display the javascript MDSplot (if file=NULL) from GO_SS-class or GO_clusters-class objects.
A static png image could be printed by setting file argument.

Value

a MDS plot.
