[R] Changing line length in Sweave output works for numeric, but not for character vectors

[Yihui Xie]

Two possible solutions:

1. Redefine the LaTeX environment so it allows wrapping (see listings
for example);
2. Manually break your long string into shorter pieces and paste()
them together, e.g. paste('long', 'long', 'string')
