Description

This method plots a gene group with genes as vertices and cosine similarities as weighted edges. Mildly informative at best :-)

plotGroup(object, ...)

## S4 method for signature 'pgVirtual'
plotGroup(object, group, kmerSize, lowerLimit, rescale,
  transform, ...)

Arguments

object

A pgVirtual subclass

...

Parameters to be passed on to igraphs plotting method

group

Name or index of the gene group to plot

kmerSize

The kmer size to use for similarity calculations

lowerLimit

The lower threshold for similarity below which it will be set to 0

rescale

logical. Should the similarity be rescaled between lowerLimit and 1

transform

A transformation function to apply to the similarities

Value

Called for the side effect of creating a plot. Invisibly returns an igraph object with all visual parameters set as node and edge attributes.
