\begin{frame}[t]{Course introduction}

\begin{block}{Course agenda}
	\begin{itemize}
		\item Object-oriented programming in \R: S3 and S4 class systems
		\item Package development in \R: creating and documenting packages
		\item Other advanced topics: testing, debugging, profiling, C/C++ interface, 
		      parallel computation
		%% \item This is an \textbf{intensive} course
	\end{itemize}
\end{block}

\begin{block}{Objectives}
	By the end of the course you should have created a working package written
	in the S4 class system. 

	\bigskip
	You should be able to use the code as a template for your own work. Our
	example has been chosen for demonstrative purposes. 

\end{block}

\begin{frame}[shrink]{Course working example: "sequences" package}
\begin{block}{Working example}
	We will make a simple package to handle sequence data.
	\smallskip

	This package will be able to load a FASTA file and based on sequence type
	do some operations, like finding the sequence length or reverse sequence.
	For simplicity we will manipulate single sequences only.
\end{block}
