I'm having trouble using lm function in my code. How can I debug this?

I keep getting an error message when I try to use the lm function to perform a regression. I get the message "unexpected numeric constant". How I can I debug this?

You could turn your issue and question into a self-contained reprex (short for reproducible example)? It will help us help you if we can be sure we're all working with/looking at the same stuff.

We'll be able to see what you tried and what is the error message.


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.

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")

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

Check for any typos, specifically missing punctuation.
