+\section{Introduction}
+This document contains a minimal example of reproducible research using R.
+\section{Loading Data}
+<<loaddata>>=
+# loading data set
+data(iris)
+@
+\section{Summary of Data}
+<<summarydata>>=
+# summary of the data set
+summary(iris)
+@
+\section{A Box Plot}
+<<boxplot>>=
+# building a box plot
+boxplot(iris$Sepal.Length~iris$Species)
+@
+\section{A Table}
+<<table,results='asis'>>=
+# loading xtable package
+require(xtable)
+# creating a table
+tab<-table(iris$Species)
+# buiding a table with all data

+\end{document}
 </code>
+Save the commands above  into a file called report.rnw and compile it into a LaTeX document according to the commands below.
+<code>
+library(knitr)
+knit("report.rnw")
+</code>
+This will generate a .tex file that can be processed by a LaTex editor!
+For linux and mac users, you can run :
+<code>
+> tex2pdf report.tex
+</code>
+to convert the result into a pdf
