risk.ratio.test: Risk Ratio Test for single 2 x 2 table
In clayford/bme: Biostatistical Methods in Epidemiology

Performs a test of the null that the risk ratio between two groups in a 2 x 2 table is 1.

1	risk.ratio.test(data, conf.level = 0.95, Wald = TRUE)

`data`	a 2 x 2 matrix.
`conf.level`	confidence level of the returned confidence interval. Must be a single number between 0 and 1. Default is 0.95.
`Wald`	a logical indicating whether to use the Wald or Likelihood Ratio Test. Default is TRUE.

A list with class "htest" containing the following components:

statistic: The chi-square test statistic.
parameter: The degrees of freedom of the approximate chi-squared distribution of the test statistic.
p.value: The p-value of the test.
estimate: The unconditional maximum likelihood estimate of the risk ratio.
null.value: The null risk ratio, which is currently set to 1.
alternative: A character string describing the alternative hypothesis. Currently only "two.sided".
method: A character string indicating the method employed.
data.name: A character string giving the name of the data.
