\title{ Pairwise Wilcoxon rank sum tests}
\description{
  Calculate pairwise comparisons between group levels with corrections
  for multiple testing.
}
\usage{
pairwise.wilcox.test(x, g, p.adjust.method = p.adjust.methods, \dots)
}
\arguments{
  \item{x}{ Response vector }
  \item{g}{ Grouping vector or factor }
  \item{p.adjust.method}{ Method for adjusting p values (see
    \code{\link{p.adjust}}) }
  \item{\dots}{Additional arguments to pass to \code{\link{wilcox.test}}.}
}
\value{
  Object of class \code{"pairwise.htest"}
}
\seealso{ \code{\link{wilcox.test}}, \code{\link{p.adjust}}}

\examples{
attach(airquality)
Month <- factor(Month, labels = month.abb[5:9])
## These give warnings because of ties :
pairwise.wilcox.test(Ozone, Month)
pairwise.wilcox.test(Ozone, Month, p.adj = "bonf")
detach()
