[R] Plotting Factors -- Sorting x-axis

Hi,

Say I have a factor with 20-levels: 1, 2, 3, ..., 20, called foo.

If I do 
  plot(foo)
it will draw a barplot.  But the x-axis is sorted alphanumerically, i.e. 
1, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 2, 3, ..., 9, which is not what 
I want.  I'd like to x-axis to be in the order of 1 ~ 20 numerically.  So, 
the question is, how do I change the order on the x-axis in this case?

Cheers,

Kevin
