[BioC] Venn Diagram Code

[Anthony Bosco]

To get a venn diagram for three lists of genes use the following code


library(limma)

list1 <-list of probe ID
list2 <-list of probe ID
list3 <-list of probe ID

dooby.all <- union(list1,union(list2,list3))
dooby.mat <- matrix(0,nrow=length(dooby.all),ncol=3)
colnames(dooby.mat) <- c("list1","list2","list3")
for (i in 1:length(dooby.all)) {
dooby.mat[i,1] <- dooby.all[i]%in%list1
dooby.mat[i,2] <- dooby.all[i]%in%list2
dooby.mat[i,3] <- dooby.all[i]%in%list3}
dooby.ven <- vennCounts(dooby.mat)
vennDiagram(dooby.ven)
