Hello world:
Has anyone used hex notation within R to represents integers?
Cheers,
Steve Vejcik

Thanks for your advice.  Unfortunately, your answers are inconsistent:
as.numeric(0x1AF0) returns a decimal value for a hex string. I'd like
to do the opposite-use hex notation to represent a decimal.
e.g.
x-0x000A
y-0x0001
x+y=0x00B
 
 Cheers.

 That's a spectacularly vague question.  Short answer: yes.
 
  as.numeric(0x1AF0)
 [1] 6896
 
 (which BTW is system-dependent, but one person used it as you asked).
 
 PLEASE read the posting guide and try for a `smarter' question.

 You don't understand how R works:
 
 x - as.numeric(0x1AF0)
 
 produces an number, not its decimal representation.  A number is a number 
 is a number irrepsective of the the base of its character representation.
 
as.numeric(0x1AF0) returns a decimal value for a hex string.
If you prefer, substitute the word shows for returns.

  to dothe opposite-use hex notation to represent a decimal.
  e.g.
 x-0x000A
 y-0x0001
 x+y=0x00B
 
  Cheers.

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.

 You don't seem to get the point.  as.numeric() is a function that _returns_
 a _value_.  How you want that _value_ to be _shown_ is a different matter.
 Would you substitute `I gave the money to the cashier' with `I showed the
 money to the cashier'?
