Quickly creating holiday data frame for Prophet as a custom R data frame

#1

To create a holiday data frame for time series forecast with Prophet, there are many ways, but one way is just writing an R script and run it as a custom R data frame.

Example R script:

tibble::tibble(holiday='special_sale_day',
  ds=as.Date(c('2021-01-01', '2021-01-30', '2021-03-30','2021-04-30', '2021-05-30','2021-09-30')),
  lower_window = 0,
  upper_window = 1)

Then you can specify this holiday data frame from a Prophet forecast step.
