\title{Convert between Odds ratios and Risk ratios}
\usage{
oddsratio_to_riskratio(OR, p0, log = FALSE, ...)

riskratio_to_oddsratio(RR, p0, log = FALSE)
}
\arguments{
\item{OR, RR}{Risk ratio of \code{p1/p0} or Odds ratio of \code{odds(p1)/odds(p0)},
possibly log-ed. \code{OR} can also be a logistic regression model.}

\item{p0}{Baseline risk}

\item{log}{Take in or output the log of the ratio (such as in logistic models).}

\item{...}{Arguments passed to and from other methods.}
}
\value{
Converted index, or if \code{OR} is a logistic regression model, a
parameter table with the converted indices.
}
\description{
Convert between Odds ratios and Risk ratios

\examples{
p0 <- 0.4

(OR <- probs_to_odds(p1) / probs_to_odds(p0))
(RR <- p1 / p0)

riskratio_to_oddsratio(RR, p0 = p0)
oddsratio_to_riskratio(OR, p0 = p0)

m <- glm(am ~ factor(cyl), data = mtcars,
         family = binomial())
