[R] Value of 'pi'

[Joshua Wiley]

Dear Vincy,

I hope that in school you also learned that 22/7 is an approximation.
Please consult your local mathematician for a proof that pi != 22/7.
A quick search will provide you with volumes of information on what pi
is, how it may be calculated, and calculations out to thousands of
digits.

Cheers,

Josh
