How to change a venn command into a named object that can be plotted like a lattice object
...as union of both sets universe <- sort( unique( c(set1, set2) ) ) Counts <- matrix(0, nrow=length(universe), ncol=2) colnames(Counts) <- names for (i in 1:length(universe)) { Counts[i,1] <- universe[i] %in% set1 Counts[i,2] <- universe[i] %in% set2 } vennDiagram( vennCounts(Counts),main=title,... ) } # How I draw the Venn diagram Venn2(cPostArrayHitsNames,cPreArrayHitsNames,names=c("Post","Pre"),title=PatientID) Unfortunately something like this doesn't work: VennPlot<-Venn2(cPostArrayHitsNames,cPreArrayHitsNames,names=c("Post",&...

This is not true for my data since toptable output shows Log fold change greater than > 2. I am certain...
