There are different types of people, and some find the default Sweave 
format easier.

For a beginner, it is best that the code and output should look the same 
in the Sweave vignette as it would look on the screen during an actual 

Windows users have access to "paste commands only".  For them the default 
Sweave vignette format is perfectly convenient -- one can easily cut and 
paste whole pages straight from pdf into the R session.

Perhaps a "paste commands only" app for Unix would keep everyone happy :)
