Yes, geom_violin does the trick. Thanks for your fast and useful reply,
Bert.

Search for "violin plots" at rseek.org [1].
There is a whole package devoted to them, many packages provide them,
and there is a geom_violin in ggplot2.
Don't know if this satisfies your aesthetic sensibilities, of course.
That's for you to decide.
Cheers,
Bert

I have a point plot where the estimated points have normally

doing this, I believe, is with geom_pointrange, as shown in my
reprex.
However, this suggests to the eye that the errors are uniformly
distributed when in fact they are normally distributed. I would
prefer
to show bell curves instead of straight lines. As far as I have been

would
appreciate suggestions as to how best to proceed.
