Thank you Gabor. I'm sorry I forgot whom to acknowledge as the author. My (limited) understanding is that rcom with rscproxy essentially give the R session the ability to look like a server, and that this scares some who are concerned with security issues. I don't want any more capability than necessary and thus wanted something less potent to clear the console.
Thanks for the insight.

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. <charles.an...@statisticalengineering.com> wrote: > Ive been using this routine for several years.
