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

[jim holtman]

This I got from a previous answer.  You require the package 'rcom'

 cls.console  <-  function() {
       if (.Platform$GUI[1] != "Rgui")
               return(invisible(FALSE))
       if (!require(rcom, quietly = TRUE)) # Not shown any way!
               stop("Package rcom is required for 'cls()'")
       wsh <- comCreateObject("Wscript.Shell")
       if (is.null(wsh)) {
               return(invisible(FALSE))
       } else {
               comInvoke(wsh, "SendKeys", "\014")
               return(invisible(TRUE))
       }
}
