Hi, wouldn't it be enough for simple purposes (as stated in the original message: "Greatest common divisor of two numbers") to use:
gcd <- function(a,b) ifelse (b==0, a, gcd(b, a %% b)) > gcd(12,4) [1] 4 > gcd(4,12) [1] 4 > gcd(123456789,987654321) [1] 9 > gcd(987654321,123456789) [1] 9 > Best, Roland On 4/17/07, Patrick Burns <[EMAIL PROTECTED]> wrote: > > S Poetry has a function for that. > > > Patrick Burns > [EMAIL PROTECTED] > +44 (0)20 8525 0696 > http://www.burns-stat.com > (home of S Poetry and "A Guide for the Unwilling S User") > > AbouEl-Makarim Aboueissa wrote: > > >Dear Sir/Madam: > > > >Could you please let me know which function shall I use to get the > >Greatest common divisor of two numbers. > > > >Thank you so much for your attention to this matter, and i look forward > >to hear from you soon. > > > >Regards; > > > >Abou > > > > > >========================== > >AbouEl-Makarim Aboueissa, Ph.D. > >Assistant Professor of Statistics > >Department of Mathematics & Statistics > >University of Southern Maine > >96 Falmouth Street > >P.O.
