почему R studio отлично работает с датафреймами, но не работает с файлами Excel, используя «глянцевый» и «высокий чартер»?

Я пытаюсь создать интерактивный график, используя highcharter и зависеть от выбора входа. Приведенный ниже код прекрасно работает с фреймом данных, но после загрузки файла Excel R studio не может выполнить «функцию количества», вы можете попробовать эту таблицу, которая содержит точно такие же данные
