8.2 Graphical Parameters

R is very flexible in creating figures. There are different parameters that can be set to modify default settings such as plotting symbols, line types, or line widths.

Check out the URL QuickR Graphical Parameters for a more detailed description of the graphical parameters.

One way of seeing everything that is pre-set in R is with:

par()

Understanding the meaning of all of these symbols is beyond the scope of this chapter. If you are interested, you can find more detailed description by typing help(par) in R.

And if you are going to play around with the different settings, then best to start with this statement:

opar <- par() # saves default settings (if do first)

This way you have saved the default parameters and can reset them by reversing the code.

par(opar)  # restores default settings

Otherwise, you can always restart R to reset the parameters.
