[R-sig-Geo] pieSP: non-finite coordinates

[Jue Lin-Ye]

Greetings!

I am working with the following code. I am having an error called
"non-finite coordinates". May you tell me what does it exactly mean and how
to fix it?

On the other hand, I see that my original percentages in "pie.chart" is
changed when converting to "pies" (I have written them both in boldface).
Why does this happen and how can I fix it?

Thank you in advance!
