R help - Oct 2005 - Relative Risk and Confidence Intervals

Dear all,

Despite searching the fullrefman file I have been unable to locate a 
function to calculate the relative risk and confidence intervals from a 
simple 2 by 2 contingency table. Can anyone tell me how this is done.

Thanks in advance

Malcolm

Malcolm, Install the 'epitools' package and use the 'epitab'
function,
and use method="riskratio"
