RStudio suddenly stopped showing plots in the plot pane

Question

RStudio is not showing the generated plots in the plot pane anymore. Instead they open in a separate file with the name "Quartz". Here\'s my session info.:

Answer 1

For me, it worked when I first closed all the devices @udit-gupta. Recursively closing all the devices after finding the devices.

dev.cur()
dev.off(i) #where i = index of device to be switched off

get the device back with

getOption("device")

or

dev.set(which = dev.next())

Answer 2

Try running this:

dev.off()

Check if it works:

plot(rnorm(50), rnorm(50))
