\begin{itemize}
    \item \textbf{DATATEXT}: Harvard

\frametitle{SAS \emph{versus} R}
%\framesubtitle{} 
\begin{itemize}
    \item R is like a motorcycle.
    \item SAS is like a military Humvee. \pause
    \item Except it doesn't break down.

\frametitle{SAS File Types}

\begin{itemize}
    \item Raw data file  
    \item Program file
    \item Log file 
    \item Results file \pause

\frametitle{We work with these files}
% \framesubtitle{} 
\begin{itemize}

{\small
    \item \textbf{Raw Data File}: A file consisting of rows and columns of numbers; or maybe some of the columns have letters (character data) instead of numbers. The rows represent observations and the columns represent variables.\pause
 
    \item \textbf{Program File}: A file consisting of commands that the SAS software tries to follow. You create this file with a text editor. The program file contains a reference to the raw data file (in the infile statement), so SAS knows where to find the data. Program files have names like \texttt{reading1.sas}. \pause

    \item \textbf{Log File}: This file is produced by every SAS run, whether it is successful or unsuccessful. It contains a listing of the program file, as well any error messages or warnings. It will have a name like \texttt{reading1.log} or \texttt{reading1-log.html}.\pause
 
    \item \textbf{Output File}: The list file contains the output of the statistical procedures requested by the program file.  Output files have names like \texttt{reading1-Results.pdf}, \texttt{reading1-Results.rtf}, or \texttt{reading1-Results.html}.

\frametitle{SAS University Edition}
%\framesubtitle{} 
\begin{itemize}
    \item This is new.
    \item It seems to be the full version.
    \item It's free of charge to anybody with a university email address.

\frametitle{Features of SAS University Edition}
%\framesubtitle{} 
\begin{itemize}
    \item SAS lives in a virtual linux machine.  \pause
    \item You interact with it through a browser interface called SAS Studio. \pause
    \item With SAS running in the virtual machine, you point your browser to a localhost address. \pause
    \item The virtual linux machine is a web server. \pause
    \item It looks like you are on the Internet, but everything is happening inside your computer. \pause
    \item This way, it is really platform independent. \pause
    \item You get your data into SAS via a shared folder, \pause
           shared between the virtual linux machine and your physical machine.
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{More comments}
%\framesubtitle{} 
\begin{itemize}
    \item It’s a big download -- around 1.8 GB. \pause
    \item Actually it’s two downloads. \pause
    \item First, download the virtualization software, free from Oracle or VMWare. \pause Do this first, \emph{before} downloading SAS. \pause 
    \item Oracle's VirtualBox is recommended. \pause
    \item The SAS download site has good instructions. Follow them \emph{carefully}, because details matter. \pause
    \item Once you connect to localhost, see the FAQ. \pause
    \item Do this \emph{before} starting the SAS software. \pause
    \item The FAQ is actually a well-organized manual. \pause
    \item Set up a shared folder according to instructions, and only then start SAS up for the first time.
\end{itemize}
\end{frame}


\begin{frame}
\frametitle{Possible problems}
%\framesubtitle{} 
\begin{itemize}
    \item Slow or flaky internet connection. If it does not work the first time, try again. \pause
    \item The virtual machine requires 1GB of RAM. \pause
    \item Trouble with older operating systems? \pause
    \item Not available in the computer labs. \pause
    \item[] 
    \item You can use SAS on \texttt{utstat} instead if you wish. \pause
    \item There's also a version of SAS University Edition that runs on Amazon Web Services.
\end{itemize}

\frametitle{Important Rule}
%\framesubtitle{UTM only} 
\begin{itemize}
    \item You may not use a classmate's SAS to do your work for this course. \pause
    \item It's too easy to see each other’s program code. 
    \item You must have your own installation. \pause
%    \item[] 
    \item If two people use the same installation of SAS University Edition, they will both get zero for the assignment.
