There are various alternatives available; you can also write your own, 
by modifying the standard one.

Generally there are lots of possibilities for customizing within the 
standard one; e.g. y.intersp will affect the line spacing, using a 
negative value for inset (together with xpd=NA) will allow the legend to 
be moved outside the plot.
