Hi Uwe.

As you suggested in a private mail, the reversed big.mark looks like a bug. I've fixed it for R 2.13.0.

Dear Uwe,

Actually I expected

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

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

this I also tried :-)


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 = ",\\\\")

but then I get "10\\,000" instead of "10\,000".

No, you get "10\,000" which is represented by R when printed as
"10\\,000". If you want it as output export it by write......() or just
use cat() as in:

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

Uwe



   The reason why I want to have "10\,000" is for use in LaTeX. If I
produce the format "10\\,000" in a table, then xtable gives me
10$\backslash$,000 for the corresponding cell entry, which is wrong :-(.
Do you know a trick for that?

Cheers,

Marius

Hi,

why does format(10000, big.mark = "\\,") not give me "10\,000"? How can I get this kind 
of "big.mark"?

Cheers,

Marius
