[R] hex format

[Steve Vejcik]

I understand that point.

Again:

I would like to have numbers represented
to me in hexidecimal format, not decimal format.
This was my original query and I think it's clear.
Let me try another variation:
I would like R to recognize that I am using
hexadecimal notation when I type a number at the
keyboard.
I would like R to have the ability to show me an
integer expressed in hexadecimal format.
