A little bit of research wouldn't hurt:

http://en.wikipedia.org/wiki/Word_wrap#Algorithm

You can split text in R with strsplit, get the length of strings with
nchar, and add up the lengths with + or sum.

 The greedy algorithm just takes as many strings until the next one
would go over the line length, and then spits those out and a new
line, and carries on. The other algorithm on Wikipedia looks much more
fun.
