Share:

Description

Plots a Venn Diagram of up to three binary hit vectors.

Usage

1
vennDiag(header, listOfCols, listOfNames, plotTitle, showPlot)

Arguments

header

the header of a dataset file generated with generateDatasetFile

listOfCols

a list of binary hit vectors to compare

listOfNames

a list of character strings for the annotation of the Venn Diagram

plotTitle

the plot title

showPlot

0 or 1. 1 will open one or several plot windows in the R GUI, 0 will only save the plot(s) without opening windows

Value

The plot is saved in a pdf and a png file named after the experiment name specified in the header concatenated with the plotTitle.

The function returns the plot name.
