HCD (version 1.0)

HCDplot: plot the result of hierarchical community detection

Description

Generate dendrogram of the HCD result.

Usage

HCDplot(hcd,mode="community",labels=NULL,main=NULL,label.cex=1)

Value

No return value, called for visualization.

Arguments

hcd

The result of an HCD call.

mode

plotting community hierarchy or node hierarchy. The default value is "community", indicating plotting hierarchy between communities. Alternatively, the plot is for all nodes, which is not recommended because usually there are too many of them.

labels

the labels of the each leaf of the tree. By default, the community/node index is used. The user can also specify another sequence of characters.

main

title of the plot.

label.cex

size of the leaf label in the plot. When plotting node hierarchy, typically there are too many nodes so the labels will seriously overlap. Use a smaller size (say, label.cex=0.3) may help.
