How to reset par(mfrow) in R

Question

I set par(mfrow =c(1,2)) and now everytime I plot it shows splits it into 2 plots. How can I reset this to only show one plot.

Thanks so much.

You can also reset it by closing the graph. – Tomas Sep 25 '11 at 22:36 — Tomas, Sep 25 '11 at 22:36

You can reset the mfrow parameter

par(mfrow=c(1,1))

@akz More generally, keep in mind that each plotting device has it's own separate `par` settings. So if you are generating plots interactively in the console and you change some settings using `par(foo = bar)`, you can always start over by calling `dev.off()` and create plots on a new device. – joran Sep 24 '11 at 03:57
that's super useful. Thanks Joran. – akz Sep 24 '11 at 18:27

another useful idiom is `oldparams <- par(mfrow=c(2,1)); [do stuff]; par(oldparams)` – Ben Bolker Sep 24 '11 at 21:05

Just a heads up for anyone trying this in a R script. Sometimes there will be functions (e.g. `NbClust`) which will generate graphs for you, they actually change the value of `mfrow` and leave it; therefore your next graphs will be side-by-side. Just add `par(mfrow=c(1, 1))` after running those functions and you're good to go. – Carlos F Nov 15 '19 at 14:30

You can reset the plot by doing this:

dev.off()

This works when working interactively but can break document generation systems like knitr\pandoc. – DLKJ Jul 21 '14 at 14:46

If you do not check if there is anything to close, you will have an error. It is better to use: `if(dev.cur() > 1) dev.off()` – Antoni Nov 22 '20 at 16:11
We can use `graphics.off()` to close all devices at once. – jay.sf Apr 20 '22 at 19:37

Both dev.off() and graphics.off() works fine for me. Good luck!
