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

[Dimitri Liakhovitski]

I tried the mosaic chart:

mytotal=data.frame(x=50,y=30,z=20)
require(stats)
mosaicplot(mytotal1)

It's good, but it only creates rectangles that are stacked on top of
each other, which is not exactly what I was looking for.

Is there a R package for waffle chart?
I tried help.search("waffle") and found nothing. Also nothing on Google...

Thanks!
Dimitri
