Your suggestion got me on the right track.  The R command: 
option(width=50), sets the text width for R to 50 columns per line. 
When Sweave is run it breaks lines into 50 columns per line.  The 
only exception to this is when there is a command like 
II/MathematicaFiles/PointPatternAnalysis/")  it keeps the line in one 
piece.  It will not break a line in between the quotes in a line.  I 
will have to do that myself. 95% of the lines coded is a lot better 
then none.
