[R] clear console
hi,
I use R - 2.15(32bit), and want to make a code to clear a console.
Actually, I used to run following code to do that but after update the
version of R from 2.14 to 2.15, it doesn't work.
cls - function (t) {
require(RDCOMClient)
wsh - COMCreate(Wscript.Shell)
wsh$SendKeys(\f)
invisible(wsh)
}
cls()
or
cls - function() {
require(rcom)
wsh -comCreateObject(Wscript.Shell)
comInvoke(wsh, SendKeys, \f)
invisible(wsh)
}
cls()
Can anybody help me to solve this problem?
Thanks.

That is code that I originally posted on r-help 6 years ago--
https://stat.ethz.ch/pipermail/r-help/2006-February/088507.html
The rcom version of that code still seems to work for me and I suspect
the RDCOMClient one would work for me too except that RDCOMClient
seems not yet available for R 2.15.0 (after checking a variety of
repos using install.packages).
install.packages did install rcom and it worked although the first
time one runs it in the session it now gives an annoying popup message
which did not occur six years ago.
You might want to check what the differences are between your setup and mine:
R.version.string
[1] R version 2.15.0 Patched (2012-03-30 r58875)
win.version()
[1] Windows Vista (build 6002) Service Pack 2
packageVersion(rcom)
[1] ‘2.2.3.1.1’
packageVersion(rscproxy)
[1] ‘1.3.1’

Re: [R] clear console
Hello, Try cls2 - function(lines=25) cat(rep(\n, lines)) cls2() It's simpler, and doesn't need any special package. (In my system, R 2.14.1/Windows 7, i386 or x64, '\f' didn't work.) Hope this helps, Rui Barradas -- View this message in context: http://r.789695.n4.nabble.com/clear-console-tp4521532p4521663.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] clear console
Will
cat(rep(\n,30))
do?
This does not remove any objects from the global environment. That requires ?rm
