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

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.
