让 R 在完成任务时发送通知或者叮一声

Is there a way to make R beep/play a sound at the end of a script?

1. Throw a Beep

   install.packages("beepr")
   library(beepr)
   beep()

   The package is developped at GitHub.

   Usage

   beep(sound = 1, expr = NULL)

   Arguments

   sound character string or number specifying what sound to be played by either specifying one of the built in sounds or specifying the path to a wav file. The default is 1. Possible sounds are:

   0. random

   1. "ping"

   2. "coin"

   3. "fanfare"

   4. "complete"

   5. "treasure"

   6. "ready"

   7. "shotgun"

   8. "mario"

   9. "wilhelm"

   10. "facebook"

   11. "sword"

2. To get a message, you can use notify-send command:

   system("notify-send \"R script finished running\"")

[JackieMium]

在 ~/.Rprofile 里添加：

notify <- function(){
    cmd <- "notify-send"
    system2(cmd, args="-i emblem-default 'R Message' 'Mission Complete!'")
}

beep <- function(){beepr::beep()}

这样以后执行需要长时间跑的命令时，如果你打算去打开网页看其他东西，直接在末尾放上 notify() 任务完成时桌面会弹出通知，如果你打算玩手机，beep() 会在任务完成是发出声音（在自习室或图书馆请插上耳机谢谢）。
