strBreakInLines <- function(s, breakAt=90, prepend=\"\") {

Answer 1

For further completeness, there's:

• stringi::stri_wrap
• stringr::str_wrap (which just ultimately calls stringi::stri_wrap

The stringi version will deal with character sets better (it's built on the ICU library) and it's in C/C++ so it'll ultimately be faster than base::strwrap. It's also vectorized over the str parameter.
