Wow, Deadpan David.
How about using the escape sequence "\r"?
So shoot me. It wasn't documented in a manner that I recognized in the
places I looked.
?character
?Syntax
?Constants
And I did look at ?Quotes where "\r" is listed but did not know that
it was == cntrl-M (if in fact it is.) I assumed (probably incorrectly)
that ""\r" was cntrl-R. There was proabably a time in the past when I
could have told you a lot of the decimal and maybe even hexadecimal
equivalents for <cr>, <lf>, <beep>, but those days are behind me.
Keep in mind that Ctrl-M is used as the end-of-line character on
some operating systems, so accomplishing this may not be portable,
and you didn't specify your operating system. On the three main
platforms (*nix, Windows/DOS, and Mac), "\r" should work, but "\n"
may get munged.
What? I very much doubt that any of those systems will not handle "\n"
as expected. "\r" on the other hand I'm not so sure of.

Dear R-helpers,
I want to append a Ctrl-M character to a string and then save it to
a text
file.
mystring<-"This is a test."
# How do I add a Ctrl-M to it in the end ??
cat(mystring,file="testfile")
cntrl_m <- intToUtf8(13)
cat(cntrl_m,file="testfile")
The resulting file seems to have a "blank line" in my editor.
