在多图窗口中绘制到特定图? [英] Plot to specific plot in multiple-plot window?

问题描述

如果我使用par(mfrow=...)创建一个多图窗口，是否可以将数据发送到特定图(即左下角的那个")或该图始终必须是顺序图? R是否有一个像这样的软件包?

If I create a multi-plot window with par(mfrow=...), is it possible to send data to a specific plot (i.e. "the one in the lower left corner") or is the plotting always necessarily sequential? Is there a package for R that does something like this?

对于那些感兴趣的人来说，这个问题是由于R是一个单线程应用程序而不是实时可视化的理想选择而引起的.我有多个实时数据流从外部源进入R，这会异步生成数据(因此，数据流并非总是以相同的顺序出现).导致R每次更新时都围绕数据可视化图的顺序翻转.

For those that are interested, this problem arises out of the fact that R is a single-threaded application and is not ideal for real-time visualization. I have multiple real-time data streams coming into R from an outside source that produces the data asynchronously (and therefore the data streams don't always come in the same order). This results in R flipping around the order of the data visualization plots every time it updates.

推荐答案

您可以使用split.screen():

par(bg = "white") # erase.screen() will appear not to work
                  # if the background color is transparent 
                  # (as it is by default on most devices).
split.screen(c(2,1)) # split display into two screens
split.screen(c(1,3), screen = 2) # now split the bottom half into 3
screen(1) # prepare screen 1 for output
plot(10:1)
screen(4) # prepare screen 4 for output
plot(10:1)
