the error...

Error in `purrr::map2()`:

Run `rlang::last_trace()` to see where the error occurred.

where it gets stuck...

  } else {

    stop("dataframe has a variable for which the class could not be determined")

  }

I encountered this when a data frame column was type logical. I am not sure there is a programmatic way to address this since there is not a way to know what the column actually reflects. I think best would be to add a message in the stop() that the error could be caused by a type logical and that the user should check the data frame for that column type.

Something to address in a future update.
