[R] fractional calculations

[Federico Calboli]

Hi All,

is there a function in R that allows me to work with fractions without 
transforming them to floats (or whatever) in between?

Something that would calculate something like:

(1/2 + 1/8) * 1/2 = 5/16

without ever transforming to 0.5 and 0.125?

Best,

Federico
