[R] Why is format(10000, big.mark = "\\,") not 10\,000?

[Uwe Ligges]

Actually I expected

format(10000, big.mark = "\\\\,")

to work (you need to double excape the backslashes here).

But the two characters are reversed due to the code in prettyNum(). Not 
sure if it is expected, but the user was probably not expected to use 
more than a single character as the big.mark.

You can get it right by reversing as in:

format(10000, big.mark = ",\\\\")
