degreeDistCC: Degree distribution of the GO cellular component (CC) terms on a GO level
Description
For a directed graph, the in-degree nodes are the nodes which have edges coming into them
and the out-degree nodes are those which have edges going out of them. The degreeDistCC
function shows the distribution of these degrees over a particular GO level. A bar plot is obtain
which shows how many nodes in the GO level have a certain degree k.
