Remove box frame from vennDiagram plot with limma

Question

There is no option with vennDiagram() in the limma package to remove the box frame from the Venn diagram. So can anyone tell me how I can adjust the source code to fix that? I also want to remove the number in the corner.

I appreciate it.

Answer 1

Here is a quick&dirty fix. I modified the vennDiagram source code, and created a new function my.VennDiagram which I left as a GitHub gist (on account of the vennDiagram code being rather long).

Here is an example based on the example given in the vennDiagram documentation.

library(limma)
Y <- matrix(rnorm(100*6),100,6)
Y[1:10,3:4] <- Y[1:10,3:4]+3
Y[1:20,5:6] <- Y[1:20,5:6]+3
design <- cbind(1,c(0,0,1,1,0,0),c(0,0,0,0,1,1))
fit <- eBayes(lmFit(Y,design))
results <- decideTests(fit)
a <- vennCounts(results)

library(devtools)
source_gist("https://gist.github.com/mevers/9c846e6293db44dd37695c46b8f2b6a2")
my.vennDiagram(a)

I make no claim that this works for all cases. You may need to make some more adjustments.
