Sweave does not allow line breaks after forward slashes ("/"). This might lead
to a long "substring" of a command that cannot be wrapped. Hence, Sweave either
keeps this long "substring" in the current line and produces a too long line or
it moves the entire "substring" in the following line and leaves the current
line rather empty. This problem can be solved if Sweave is allowed to introduce
line breaks after forward slashes. (I guess that this problem can also be solved
if parse() adds a blank after a forward slash.)

Example: 
The following expression cannot be wrapped by Sweave:

mean(myDataframe$myFirstVariable)/mean(myDataframe$mySecondVariable)


Thanks for the great software packages (R, Sweave, ...),
Arne
