plotting

I have two questions for you.  Firstly I'm having troubles trying to plot more
then 1 graph.  I'm attempting to make a plot with 9 panels, but i have no clue
what type of code to use.
Secondly i was wondering if there was some code to generate random numbers
between two defined intervals and then have R chose one randomly in a program. 
If you could answer either of these questions for me I would appreciate it.
