It's been some time since I used R and I feel a bit rusty. I wrote a function called "sentence_match" that seemed to work well when applied to a single piece of text. You can see that by running the section titled
"Working code". I thought that it might be possible easily to apply my function to a data set (tibble or df) but that doesn't seem to be the case. My unsuccessful at...
