It depends upon the type of plot (scatter, lines, bar, etc.) and whether
or not you are using R's base graphics or lattice graphics.

With more information, we can offer specific guidance.

For example, with base graphics, you can add additional plot components
with:

?lines
?points
?segments
?matpoints (Note also matplot() on the same page)
?curve
?arrows

A good starting place would be Chapter 12 "Graphical Procedures" in An
Introduction to R, which is available within your R installation (on
Windows from the GUI menus) or from the Documentation links on the R
home page.

An additional resource is the R Graph Gallery:

and Chapter 3 "From Data to Graphics" by Vincent Zoonekynd here:
