In acabassi/coca: Cluster-of-Clusters Analysis

Plot area under the curve for different values of K.

1	plotDeltaAUC(deltaAUC, chosenK = NULL, fileName = "deltaAUC.png")

`deltaAUC`	Vector of the difference between the area under the curve between each value K of the number of clusters and K-1. For the smallest value considered (usually two) this is simply the area under the curve for that value of cluster number.
`chosenK`	Chosen number of clusters. If specified, a vertical line is plotted in correspondance of the indicated value. Default is NULL.
`fileName`	name of the png file
