In this way can I get correct figure? My doubt is in the resulting figure, gamma quantile are in X-axis and emperical are in Y-axis, however the values in the Y-axis are up to 15. But my maximum point in data set is 9.68. How can it be correct?

Dear Madan,

Please see the qq.plot() function in the car package.

I hope this helps,
