Hello R usuer,
The code given below superimposes a pie diagram on another plot
containing some points. However, I would like to center the pie
diagram on the xy location on the plot, but not on the center. is
there any way to re-center pic diagram.
Any suggestion or better alternative are highly appreciated.
Thank you in advance for your help.
Regards,
Bibke
