Side by Side Plotting Instead of Panel Plotting on R Base System-CodePudding

Sorry if this question was asked before but I couldn't find a similar post. I am trying to create a panel plot on R's base system. But R Studio shows my plots side by side not on a panel. So I tried to copy some codes from internet and it is still showing charts side by side. For example this codes has to create a panel plot right?

library(datasets)
par(mfrow = c(1, 3), mar = c(4, 4, 2, 1), oma = c(0, 0, 2, 0))
with(airquality, {
   plot(Wind, Ozone, main = "Ozone and Wind")
   plot(Solar.R, Ozone, main = "Ozone and Solar Radiation")
   plot(Temp, Ozone, main = "Ozone and Temperature")
   mtext("Ozone and Weather in New York City", outer = TRUE)
})

But stupid R studio is creating plots side by side. Here is a screenshot:

Probably it will be ok if I restart R session but I don't want to loose my loaded variables. Any guesses for this issue? By the way I created some plots using lattice and ggplot2 on same session (I don't know if it effects each other.)

CodePudding user response：

If you run your code in the console, you will get a panel plot. Run this code in console:

library(datasets)
par(mfrow = c(1, 3), mar = c(4, 4, 2, 1), oma = c(0, 0, 2, 0))
with(airquality, {
  plot(Wind, Ozone, main = "Ozone and Wind")
  plot(Solar.R, Ozone, main = "Ozone and Solar Radiation")
  plot(Temp, Ozone, main = "Ozone and Temperature")
  mtext("Ozone and Weather in New York City", outer = TRUE)
})

Output:

If you run this in Rmarkdown, you will also get a panel plot. Here is the code:
