[R] Unlisting a nested dataset

[Nathan Parsons]

Ista - I provided data, code, and the error being returned as per reproducible r protocol. I did not include packages, however. unnest_tokens is from the TidyText package, map/map_chr are from purrr, and everything else is from tidyverse(dplyr/tidyr/etc.)

Not sure what else I can provide to make this more clear.
