Off topic:R: How to display elements using line-breaks, instead of counts, within each circle of a Venn diagram?

Question

[rahman.safiurbd]

Hi:

I need to generate a Venn diagram with elements (not counts). So I followed this link. But the problem is elements are looking messy.

I need to know how I can generate a Venn diagram with a clear image of the elements (line breaks or space). I was looking at this but could not succeed.

Thanks,
Mahdi
