"Error in plot.new()" when stacking two simple plots

Question

I simply want to stack two simple line plots in base R. Here is what I tried:

x <- c(1:100)
y <- c(100:1)
old.par <- par(mfrow = c(2, 1))
plot(x, y)
plot(x, y)
par(old.par)

I used this method in the past successfully, but this time R throws me an error when I call plot(x, y): Error in plot.new() : figure margins too large. If I call plot(x,y) without par(...) beforehand, there is no error.

Answer 1

it's work for me plot

If you get this message in RStudio, clicking the 'broomstick' figure "Clear All Plots" in Plots tab and trying plot() again may work.
