Is there a bijection from R^n to R?

Hi,

I need a bijection from r^n to r and it does not have to be continuous. Can anyone think of one? Am struggling. I should say this is for n>1.

I confess this stuff is above me but this seems to be what you are after

This also seems to have so relevant and interesting discussion.
