R HELP! PSO Package - "Error during wrapup: incorrect number of dimensions

Hi @johannas,

I'm going to move this into General, since AFAICT, it's not directly related to the IDE (you can change it back, if I'm wrong, but, if not, this will help ensure you get the right eyeballs on your question!)

I also think it will be :+1: if you can turn this into a self-contained reprex (short for minimal reproducible example). It improves legibility, and will help us help you if we can be sure we're all working with/looking at the same stuff.

Right now the best way to install reprex is:

# install.packages("devtools")

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.

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")

For pointers specific to the community site, check out the reprex FAQ, linked to below.
