Clear R Console programmatically [duplicate]

Answer 1

Create this function:

cls <- function() cat(rep("\n",100))

Then call it:

cls()

Works with:

• Windows
• Linux
• Mac

Answer 2

I use a function for doing that, and actually have put it in {R directory}\etc\Rprofile.site so that it will always be available for use.

cls <- function() {
        require(rcom)
        wsh <- comCreateObject("Wscript.Shell")
        comInvoke(wsh, "SendKeys", "\014")
        invisible(wsh)
 }
cls()

To clear the console give

cls()

P.S. The function doesn't work the first time it's called and that's why I invoke the function immediately after declaring it in Rprofile.site. As I recall, you may be asked to install some program, in order for this to work.

Answer 3

I might be missing the point dramatically, but is simple system("clear") an easier approach? Of course, it can only be applied on Linux/Unix environments...
