windows中要么使用ctrl+L，要么使用菜单操作，函数貌似没有

谢谢啦！
好像真没有命令哦！

right click your mouse, and select "clear window", same as "ctrl+L"

正找这个命令了，谢谢

# An R function to clear the screen on RGui:
cls <- 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))
        }
}
#cls() # test
# If you want to make sure that it worked (well, not 100% sure, but...)
res <- cls()
if (res) cat("Console should be cleared now!\n")
