ggdensity::geom_hdr() fails where there is only one point in a group

geomhdr() needs at least two points per group, however, I'd rather set a higher threshold. The easiest way to get around this would be to split your data and only apply geomhdr() to categories with enough data points.

Here's an example dataset:

set.seed(42)
DF 
  within(Category  Warning: Computation failed in stathdr().
#> Caused by error in `if (any(h  ! missing value where TRUE/FALSE needed

Then if we split the data, and only apply geomhdr() on the categories that have more than 2 (or more) points, and plot the rest with geompoint() we get the following plot:
