R Multiples plot in a single varible

Question

Hi I have the next code:

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\")         


        

Answer 1

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

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.
