Vertex and Edge Group Colours

Identify Vertex and/or Edge groups by colour.

plotNET_groupColour(
  g,
  groups = NULL,
  colourV = TRUE,
  alphaV = 1,
  colourE = FALSE,
  alphaE = 0.8,
  groupColours = NULL,
  defaultEdgeColour = "grey70",
  doPlot = TRUE,
  returnPlot = FALSE
)

Arguments

g

An igraph object

groups

A named numeric vector with length(V(g)) integers representing each group, or, a named character vector describing each group. If names(groups)==NULL then the names of the vector will be set as names(groups) == V(g)$name. If V(g)$name==NULL, the names of the vector will be set by the Vertex index

colourV

Colour Vertices based on groups (default = TRUE)

alphaV

Set transparency for Vertices (default = 1)

colourE

Colour Edges based on groups. Edges connecting to vertices of the same group will be coloured as the group (default = FALSE)

alphaE

Set transparency for Edges. A single numeric, or a vector of length ecount(g) (default = 0.8)

groupColours

A list of length groups with valid colour codes

defaultEdgeColour

Default edge colour

doPlot

Plot the igraph object

returnPlot

return the ggplot2 object

Value

An igraph object with vertices and/or edges coloured by groups listed in groups
