See ?strwrap and ?paste. Also use cat() instead of print().
The double "\\" at the end of each line tells LaTeX to force a line break.
Since R will detect the "\" as an escape character, you need to double them
when cat()ing. I also add a newline ("\n") so that the output after the "\\"
goes to the next line.
