[R] hex format
Hello world: Has anyone used hex notation within R to represents integers? Cheers, Steve Vejcik __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
Re: [R] hex format
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).

I'd like 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.

RE: [R] hex format
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.

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'?
