You probably want a larger left margin.  That means increasing the 
second component of par("mar").

I'd demonstrate, but your example code isn't reproducible.

People:  you get much better answers if you post code that is easy for 
others to run.  Then they can modify it and you'll get an example that 
works, rather than speculation about what might work.  Don't rely on 
non-base packages (unless you are asking about one of them); don't post 
huge datasets or huge R scripts.  Work out what is the essence of your 
question, and extract the code to show just that.
