[R] Displaying "<=" in axis values

[Dennis Fisher]

R 3.0.2
OS X

Colleagues

In a graphic, the x-axis values
	2, 4, 6, 8, 10, 12

I would like to present these as:
	≤ 2, ≤ 4, ≤ 6, ≤8, ≤ 10, ≤ 12

I have tried to accomplish this with 
	expression 
and 
	bquote 
without success.  Can someone provide the appropriate code?  

Thanks.

Dennis
