\keyword{htest}{pairwise.wilcox.test}
\begin{Description}\relax
Calculate pairwise comparisons between group levels with corrections
for multiple testing.
\end{Description}
\begin{Usage}
\begin{verbatim}
pairwise.wilcox.test(x, g, p.adjust.method = p.adjust.methods, ...)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{x}] Response vector 
\item[\code{g}] Grouping vector or factor 
\item[\code{p.adjust.method}] Method for adjusting p values (see
\code{\LinkA{p.adjust}{p.adjust}}) 
\item[\code{...}] Additional arguments to pass to \code{\LinkA{wilcox.test}{wilcox.test}}.
\end{ldescription}

\begin{Examples}
\begin{ExampleCode}
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()
