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",...

LIMMA decideTests result zero from contrast matrix
Dear All,
I am using the LIMMA package to create 2 contrasts for my data and then calculating the vennCounts of the decideTests from the contrast.fit to be able to create venn Diagrams.
The code works fine but the summary(results) shows zeros for all i.e. no gene were up regulated or downregulated. This is not true for my data since toptable output shows Log fold change greater than > 2.
I am certai...
