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

this I also tried :-)

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