How to convert Hexadecimal values to decimal in dataframe?

Could you please turn this into a self-contained reprex (short for reproducible example)?

Currently, we can't reproduce what you're seeing — or we'd have to go through and manually try to type in the values in the image, and, even then, we can't know exactly the steps you're taking that are leading to that error message.

install.packages("reprex")

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")
