Hello! I noticed on the assignment5 page it required us to name one of the columns Cumulative.Data, however in the example code that was provided the colname was called Cumulative.data (no capitalization on data). Please see the reference screenshot below. Is there a particular way we should name the column, or should we code it to take any variation (with or without capitalization)?
Well spotted. I've fixed the error. Please be consistent with the Assignment page.
