You got it from my post here: http://tolstoy.newcastle.edu.au/R/help/06/02/21556.html Don't know why rcom's dependencies are a consideration but RDCOMClient can also handle this: cls <- function () { require(RDCOMClient) wsh <- COMCreate("Wscript.Shell") wsh$SendKeys("\f") invisible(wsh) } cls() On Sun, May 3, 2009 at 6:50 PM, Charles Annis, P.E.

cls <-

? ?comInvoke(wsh, "SendKeys", "\f")
? ?invisible(wsh)
}
cls()
Loading required package: rcom Loading required package: rscproxy This seems like overkill to me just to blank the R console, especially since I am trying to diminish the number of necessary packages to support my home-brew package. So, is there an easier way to blank the R console in Windows?
