multiple vennDiagrams in one plot R

Question

I would like to make many venn diagrams in one plot in R. I tried using the venneuler packages (and using par(mfrow=c(2,1))), however i would like that a circle in one venn diagram has the same size in all diagrams - if the value is the same.

When I do

require(venneuler) par(mfrow=c(2,1)) plot(venneuler(c(A=1, B=8, "A&B"=1))) plot(venneuler(c(A=1, C=1, "A&C"=1)))

I get enter image description here

But A in the first plot, should be same size as A and C in the second

@TylerRinker: But that will still give the same result. The problem is that the biggest value in each vennDiagram is set to fill the entire plot. John: B should have an area 8 times as big as A and C — user2335015
I tried a few techniques, but I think you may have to resort to recoding venneuler:::plot.VennDiagram by hand. Luckily, it's relatively short, and incorporating some cognizance of xlim and ylim shouldn't be too hard ... — r2evans
... perhaps the problem is in venneuler() itself, which appears to be doing the auto-scaling for you. That function is s bit more work to modify. Perhaps you could contact the maintainer? It hasn't been touched in almost four years, though ... — r2evans
Yes, that is exactly my problem. Do anyone know if there is a venndiagram package, where you can choose you own scaling? — user2335015

You can accomplish this with my r package eulerr. It returns grid graphics objects that can be arranged using the excellent gridExtra package.

library(eulerr)

p1 <- plot(euler(c(A = 1, B = 8, "A&B" = 1)))
p2 <- plot(euler(c(A = 1, C = 1, "A&C" = 1)))

gridExtra::grid.arrange(p1, p2)
