Hello,
I have to write a big sentence with cat() and I would like that R
automatically adds a new line when it is needed (when the text arrives at
the end of the window), the same as Windows Notepad does (Word Wrap).
How could I do?
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.
Also ?strwrap, along the lines of
wrap = strwrap("All the world's a stage. And all the men and women
merely players.", width=30)
cat(paste(wrap, collapse="\n"), "\n")
