Inverse probability weighting

I'm afraid I'm a little out of my depth in terms of what you're asking. If you could make a reprex, it would go a long way towards helping others help you:

A self-contained reprex (short for reproducible example) means that others can reproduce exactly what you're seeing.

install.packages("reprex")

If you've never heard of a reprex before, you might want to start by reading the tidyverse.org help page. The reprex dos and don'ts are also useful.

There's also a nice FAQ on how to do a minimal reprex for beginners, below:

What to do if you run into clipboard problems

If you run into problems with access to your clipboard, you can specify an outfile for the reprex, and then copy and paste the contents into the forum.

reprex::reprex(input = "fruits_stringdist.R", outfile = "fruits_stringdist.md")
