\title{Confidence/credible intervals from samples}
\description{
  These functions compute highest posterior density (HPDI) and percentile (PI) intervals, using samples from a posterior density or simulated outcomes.
}
\usage{
HPDI( samples , prob=0.89 )
PI( samples , prob=0.89 )
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{samples}{Vector of parameter values}
  \item{prob}{interval probability mass}
}
\details{
  Highest Posterior Density Intervals (HPDI) are calculated by \code{\link{HPDinterval}} in the \code{coda} package.
  
  Percentile intervals (PI) use \code{\link{quantile}} and assign equal mass to each tail.
