Dear List,
 
Having processed my affy data and fitted a linear model with limma, I would
like to export a Venn diagram to illustrate the number of genes in each of
my 3 comparisons. I have used the following script which outputs all the
genes that are significantly differentially expressed and is based on the
affycoretools package:
 
rslt<-decideTests(fit2, adjust.method="fdr")
vc<-vennCounts2(rslt,method="both")
vennDiagram(vc,cex=0.8)
vennSelect(mySubSet,fit2,design,rslt,method="both")

What I would like to do is to reduce the number of genes that are counted in
the Venn diagram so that only those with a 1.5 fold increase or decrease in
expression are included.
 
Please could you advise me how this can be achieved?
 
Very many thanks,

Quentin
