[R] squared "pie chart" - is there such a thing?

[Dimitri Liakhovitski]

Thanks a lot, Sarah.
I am definitely going to explore.
A quick question about
mosaicplot(matrix(c(50, 30, 20, 0), 2, 2))
mosaicplot(matrix(c(0, 50, 20, 30), 2, 2))

What are the numbers that appear on the graphs (2.1, 2.2,1.1,1.2)?
