[R] SUMMARY control L to clear the Rgui screen in Windows

[Charles Annis, P.E.]

Eternal thanks to Jim Holtman and to Gabor Grothendieck who pointed me to
this concise piece of code:

cls <- function() {
	require(rcom)
	wsh <- comCreateObject("Wscript.Shell")
	comInvoke(wsh, "SendKeys", "\014")
	invisible(wsh)
}


Perfect!

Thanks!

Subject: [R] control L to clear the Rgui screen in Windows

Greetings R-ians:

Searching the Searchable Mail Archives I discovered that ctrl L will clear
the Rgui screen, which is what I'd like to do from a print (or some similar)
statement.

Is there a mechanism to use the ctrl L clear-screen sequence in a script, or
print statement?

Thanks for your counsel.

Charles Annis, P.E.
