Solve the problem of "plot.new (): Figure margins too large" in Rstudio

The "plot.new (): Figure margins too large" issue often occurs when plotting using the plot () function in Rstudio. (1) is shown.

The problem occurs because the "plots" window in the Rstudio is too small to fit properly, or to set the Rstudio to full screen. The steps to resolve are as follows.
1. Select the "Plots" tab with the mouse, and then drag the window a little larger, as shown in (2).
