[R] Number -> Fraction

[Mauro Arnoldi]

Hi everybody!
I'm new to this list and also to the R program.

I'd like to know if there is a function able to convert results into 
Fractional form like my scientific calculator have. For example:

> 1/3
[1] 0.3333333

> function_that_return_a_fraction_from_numbers(0.3333333)
[1] 1/3

Thanks

Mauro
