pieSP: non-finite coordinates
Dear Jue, Please try to clearly define a reproducible example, next time. The problem is column with 0 values. Function pieSP can not generate coordinates for attributes of zero values. Best, Milan

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!
