[R] Turn off border on barplot

[Frank McCown]

I was wondering if there was any way to completely remove the borders 
around each bar when using the barplot function.  I understand how to 
change the color of the border (border="white"), but I need the border 
to be invisible so I can plot many skinny bars right next to each other 
with only the bar's color visible.

Thanks,
Frank
