The recent thread on how to send mail from R got me thinking about a solution to clearing the rgui console under WinXP (something I've often wanted to do and I've seen others ask about). If you create a small vb script, say called "RClear.vbs":  

Dim wsh
Set wsh = CreateObject("WScript.Shell")
wsh.AppActivate "R Console"
wsh.SendKeys "^L"  

and copy this to the %windir%\system32 directory, you can create a function in R:  

clear.console <- function() {

   system(paste(Sys.getenv("windir"),"/system32/cscript.exe rclear.vbs",sep=""),

      intern=F, invisible=T)

that will clear the the rgui console. Sorry for the redundancy if someone has already posted a similar solution.
