In this example we embed parts of the examples from the 
\texttt{kruskal.test} help page into a \LaTeX{} document:

<<>>=
data(airquality)
library(stats)
kruskal.test(Ozone ~ Month , data = airquality)
@
which shows that the location parameter of the Ozone distribution varies significantly from month to month. Finally we include a boxplot of the data:

\begin{center} 
<<fig=TRUE ,echo=FALSE >>=
boxplot(Ozone ~ Month, data = airquality)
@
\end{center}
