回答by George Dontas
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.
我使用一个函数来做这件事，实际上已经把它放在 {R directory}\etc\Rprofile.site 中，这样它就可以一直使用。
cls <- function() {
require(rcom)
wsh <- comCreateObject("Wscript.Shell")
comInvoke(wsh, "SendKeys", "4")
invisible(wsh)
}
cls()
To clear the console give
清除控制台给
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.
PS 该函数在第一次被调用时不起作用，这就是为什么我在 Rprofile.site 中声明它后立即调用该函数。我记得，您可能会被要求安装一些程序，以使其正常工作。

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...
我可能会大大错过这一点，但是简单system("clear")的方法更简单吗？当然，它只能应用于Linux/Unix环境……
