Functions and Arguments

flipdownr has one function: flipdown which contains the following arguments:

  • downto : the targeted date for the countdown. It must have the form of ‘yyyy-mm-dd’ or ‘yyyy-mm-dd hh:mm:ss`. Note that you can include the time zone (example UTC): ’yyyy-mm-dd hh:mm:ss UTC’;

  • id : the id of the countdown. Useful when you need to include many countdown objects in one document;

  • theme : The theme of the flipdown object. Two possible choices: ‘dark’ or ‘light’. Defaults to ‘dark’

  • headings : A character vector pecifying the heading related to each time part. Defaults to English headings: c(“Days”, “Hours”, “Minutes”, “Seconds”).


This article was written the 2020-10-16 (16th of October 2020) at 16:13 (GMT+1) approximately, as such the CountDown will reflect it.


flipdown(downto = "2020-11-16", id = "c1", theme = "dark")

You can add another level of precision by specifying the exact time:

flipdown(downto = "2020-11-16 22:30:00 UTC", id = "c2", theme = "dark")

You can also specify a light theme:

flipdown(downto = "2020-11-16", id = "clight", theme = "light")

You can modify the headers with the headings argument:

flipdown(downto = "2020-11-16",
         id = "cspanish", 
         theme = "light", 
         headings = c("Dias", "Horas", "Minutos", "Segundos"))
