draw stripes in a circle in R

Wed, Jun 14, 2017 10:09 AM

Sorry for that. Yes my question was whether or not and how is it possible to fill a circle of yellow stripes in R? Is it something that I have to precise in the color argument?
Thanks, best

I don't see a question. If your question is whether R supports pattern fills, AFAIK it does not. If that is not your question, ask one.
