Hatice, Thanks for your suggestion, I have added the capability to the makeVennDiagram function in ChIPpeakAnno dev version 1.9.3 to plot 4-way venn diagram for showing binding sites overlap among 4 chip-seq /chip-chip experiments. Thanks to Stephen’s, I have leveraged gplots for drawing the diagram.
