Hi Jonathan, Re: this note: no visible binding for global variable ‘datetime’
In programming and packages, it is recommended to use special versions of dplyr’s single table verbs, e.g., use `filter_()` as opposed to `filter()`. Note the underscore. The “underscore” functions use standard evaluation instead of non-standard evaluation.
