Do you have a list of files as a dataset, or are you trying to get a list of the files that are in a directory?
If the latter, you can use fs::dir_ls() (after installing fs, of course).
If you're still having trouble, a self-contained reprex (short for reproducible example) will help us help you.
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")
