18.2 venn.diagram function from VennDiagram package

A Venn diagram shows all possible logical relations between data sets.
The venn.diagram function from the VennDiagram package allows to create up to a 5-way Venn Diagram (i.e. 5 circles representing 5 data sets).

# load package
library(VennDiagram)

# Prepare character vectors
v1 <- c("DKK1", "NPC1", "NAPG", "ERG", "VHL", "BTD", "MALL", "HAUS1")
v2 <- c("SMAD4", "DKK1", "ASXL3", "ERG", "CKLF", "TIAM1", "VHL", "BTD", "EMP1", "MALL", "PAX3")
v3 <- c("PAX3", "SMAD4", "DKK1", "MALL", "ERG", "CDKN2A", "DENR", "NPC1", "NAPG")

# Create a list of vectors
vlist <- list(v1, v2, v3)
names(vlist) <- c("list1", "list2", "list3")

# 2-way Venn
venn.diagram(vlist[1:2], 
    filename="Venn_2way.png",
    imagetype="png")

# 3-way Venn
venn.diagram(vlist, 
        filename="Venn_3way.png",
        imagetype="png")
