如何在R中终止绘图过程?

Sometimes I have very heavy plots in a device in my R session. When, for instance, I change the size of the window where the device is pointing to it gets redrawn quite slowly. Typing Ctrl+C does not seem to kill the plotting task.

有时我在R阶段的设备中有很重的情节。例如，当我改变设备指向它的窗口的大小时，重新绘制速度会很慢。键入Ctrl+C似乎不会终止绘图任务。

Is there a way of "cancelling" or killing a plot in R while it is being drawn?

是否有一种方法可以“取消”或杀死正在绘制的R中的阴谋?

Edit: I am using Linux and just the normal R shell from a terminal (gnome-terminal usually). Regardless of what system I use I guess there can be many answers covering each system or an integrative answer which shows how to perform this operation on any system.

编辑:我使用的是Linux和普通的来自终端(通常是gnome-terminal)的R shell。不管我使用什么系统，我猜可能会有很多答案覆盖每个系统或一个综合的答案，它显示了如何在任何系统上执行这个操作。

there is a kill function in package fork http://cran.r-project.org/web/packages/fork/index.html

在package fork http://cran.r project.org/web/packages/fork/index.html中有一个kill函数

Now since R doesn't spawn a seperate gnuplot process or smth that you can kill i think you will be able to send a SIGINT to the actual R process to stop the computation. so INT is usually 2 on unices and you want to send a kill -2 to the PID of the R process.

既然R没有生成一个单独的gnuplot进程或者smth，你可以杀死它，我认为你可以向实际的R进程发送一个SIGINT函数来停止计算。所以INT在unices上通常是2你想把kill -2发送给R进程的PID。

the bad way to do that would be through a

不好的做法是通过a

system('pkill -2 R')

系统(pkill 2 R)
