Insert line breaks in long string — word wrap

Question

Here is a function I wrote to break a long string into lines not longer than a given length

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


        

Answer 1

You can look at e.g. the write.dcf() FUNCTION in R itself; it also uses a loop so nothing to be ashamed of here.

The first goal is to get it right --- see Chambers (2008).
