Relative risk and its score confidence interval of the two groups without stratification
RRmn1(y1, n1, y2, n2, conf.level=0.95, eps=1e-8)
There is no standard error.
proportion from the first group, y1/n1
proportion from the second group, y2/n2
relative risk, p1/p2
lower confidence limit of RR
upper confidence limit of RR
positive event count of test (the first) group
total count of the test (the first) group
positive event count of control (the second) group
total count of control (the second) group
confidence level
absolute value less than eps is regarded as negligible

It calculates the relative risk and its score confidence interval of the two groups. The confidence interval is asymmetric, and there is no standard error in the output. This does not support stratification. This implementation uses uniroot function, which usually gives at least 5 significant digits. Whereas PropCIs::riskscoreci function uses cubic equation approximation which gives only about 2 significant digits.
