Tidyverse ggplot() help: How to segment each column in the geom_bar()

It will be much easier to troubleshoot this if you can put it in a reproducible example, which you can do with reprex. That way your input, output, and charts will all be self-contained so anyone can just copy and paste to replicate exactly what you're doing.

You can install reprex, as shown 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")
