单个变量中的 R 倍数图 [英] R Multiples plot in a single varible

问题描述

我有下一个代码:

par(mfrow=c(1,3))
plot(BCxyz[,1], BCxyz[,2], main="Bray-Curtis 1:2", pch=20, cex = 3, col=c("blue", "green", "red", "yellow")[Metadata$SampleType])
plot(BCxyz[,1], BCxyz[,3], main="Bray-Curtis 1:3", pch=20, cex = 3, col=c("blue", "green", "red", "yellow")[Metadata$SampleType])
plot(BCxyz[,2], BCxyz[,3], main="Bray-Curtis 2:3", pch=20, cex = 3, col=c("blue", "green", "red", "yellow")[Metadata$SampleType])

通过这种方式，我得到了一个包含 3 个图的图形，所以我只想将图形(其中包含 3 个图)添加到一个变量中，例如:

in this way I get a figure with 3 plots, so I just want to add the figure (with 3 plot in it) in a single variable, something like :

figure1 <- (mfrow=c(1,3)........)

每次我调用图 1 时，在一个图中打开 3 个图 !!!!!!

and each time that I call figure1, open 3 plot in a single figure !!!!

谢谢

推荐答案

您可以使用 recordPlot 保存当前绘图并稍后调用.

You can use recordPlot to save the current plot and recall it later.

par(mfrow=c(1,3))
plot(1) ; plot(2); plot(3)
figure1 <- recordPlot()
# view then close the plot window, just to prove that redrawing it works

figure1             # redraws it when interactive on the console
replayPlot(figure1) # same thing
print(figure1)      # indirect, calls replayPlot

最后两个命令在控制台上具有相同的结果，但是如果您要以编程方式重放"绘图(例如，在 {...} 代码块或函数中)，你应该直接使用 replayPlot 函数.figure1 在控制台上单独工作的原因(没有 print 或 replayPlot)是 figure1 是类"recordedplot"，以及 base-R grDevices::print.recordedplot S3 方法直接调用 replayPlot.

The last two commands have the same result on the console, but if you are going to "replay" the plot programmatically (e.g., within {...} code-blocks or functions), you should use the replayPlot function directly. The reason just figure1 works by itself on the console (no print or replayPlot) is that figure1 is of class "recordedplot", and the base-R grDevices:::print.recordedplot S3 method calls replayPlot directly.
