How can I convert the date into weekday in numeric form? Similar question here:Find the day of a week
When run on my computer, the out put look like this:
> weekdays.Date(as.Date("2016-12-31"))
[1] "星期六"
But I am designing a program that will be dispatched to people from all over the world.
Same code run on different computer might give different result:
> weekdays.Date(as.Date("2016-12-31"))
[1] "Saturday"
This makes the situation complicated if I need to consider putting a translation chunk in my code.
I wonder if there is a way that, when doing the conversion it returns weekdays in numbers. For instance, Monday is 1, Tuesday is 2 ..., Sunday is 7.
