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

Hello world: Has anyone used hex notation within R to
represents integers?
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.
