Reset par to the default values at startup

Normally when I make my own plot functions, I make a construct :

op <- par("mypar"=myvalue) on.exit(par(op))

which is the standard way of reverting the par to the previous values. Imagine you've been running some functions that did change some of the pars, and you need to reset to the default values at startup in R. What is the convenient way of doing so?

Or in other words : how does one reaches the default values for par()?

What is the par function in R?

R par() function R programming has a lot of graphical parameters which control the way our graphs are displayed. The par() function helps us in setting or inquiring about these parameters. For example, you can look at all the parameters and their value by calling the function without any argument.

Every time a new device is opened par() will reset, so another option is simply do dev.off() and continue.
