Dear listers,

I have two questions:
(1)
Is there a way in R to change the base-n of the calculations. I wnat to run
some calculations either in binary (base-2) or base-4. Is there a way to
specify that in R - to chnage from the decimal?

(2)
I also want to extract the digits from a larger number and store them as a
vector.
I could do it through converting top string, parsing the string and
converting back. Is there another way.
It would look something like that:
> a<-1234
> a
[1] 1234
> b<-foo(a)
> b
[,1] [,2] [,3] [,4]
[1,] 1 2 3 4

Thanks!

Andrej
