Saving results using npregress kernel

[Mark Toma]

Hi all,
I am using Stata 17 and am having trouble saving results from npregress kernel.

  npregress kernel runs radius
  margins, at(radius = (0(.01) 3)) vsquish saving("...")
  marginsplot, recast(line) recastci(rarea) saving("...")

I get this error message after the margins command:

saving() not allowed with margins after npregress kernel
r(198);

Is there a workaround this problem?

Thanks,
Mark Toma
