Save Plot in Data Object in Base R (Example)
In this tutorial you’ll learn how to store a graphic in a data object in R programming.

Let’s jump right to the example!
Example: Save Graphic in Data Object Using recordPlot Function
The following R programming code explains how to record a Base R plot in a data object by applying the recordPlot function.
plot(1:5, 1:5) # Create plot
Figure 1 shows the output of the previous R code – a simple plot created with the basic graphic options of the R programming language.
If we want to save this plot in a data object, we can use the recordPlot function as follows:
my_plot <- recordPlot() # Save plot in data object
Let’s test if it worked! First, we need to remove the plot that is already drawn in RStudio:
plot.new() # Create empty plot window in RStudio
Now, we simply need to call the data object, in which our plot is stored, to recreate the plot:
my_plot # Draw saved plot
Our plot should be shown again in your RStudio environment.

Hi Joachim, do you know whether there is a way to use plots that were recorded in the way you described for allocation in a grid of multiple plots?
I tried to use recordPlot() for three different plots that I now would like to compose together to one plot, e.g. using the layout() function. This did not work, however. Once I try to draw a saved plot after running layout() or par(mfrow)), it just takes all the space of the plotting device.
Could you help with that?
Thank you for the interesting question, and sorry for the delayed response, I just came back from vacation. Do you still need help with this?
I happen to have the same question. Could you explain please? Thank you very much.
I have not found a solution for the layout function. However, you may combine your Base R plots in a grid of plots using the cowplot package.
Please have a look at the example below:
I hope that helps!
