Визуализация даты в блестящей

Question

Я хочу создать блестящее приложение на основе этого: пример . Вот мой CSV-файл с датой: дата

Мне нужна помощь с этим кодом. Прежде всего, я думаю, что я сделал много ошибок. Я не знаю, как это сделать, что пользователь может выберите оси системы координат из: Год, Возраст, Рост, Вес. И я не уверен насчет остальной части кода. Комментарии взяты из исходного кода.

ОБНОВЛЕНИЕ : Я создаю файл global.R

axis_vars <- c(
  "Year" = "Year",
  "Hight"="Hight",
  "Weight"="Weight",
  "Age"="Age"


)
