Ah!  That's so much simpler.  Thank you.

Just try setting 

ylim(ymax, ymin)

instead of explicitly mucking with the ticks.  Eg,

I'm trying to make a plot where instead of the y-axis being oriented in 
the traditional sense (large numbers on top, small on bottom) it needs 
to be oriented in the reverse sense (small numbers on top, large on bottom).

Now, my first thought on how to do this was the following:

 >>>plot(x,-y)
 >>>pos,lab = yticks()
 >>>yticks(pos,map(str,-array(pos)))

This works, but if I've set a specific y-axis limit range before 
reversing the labeling, the yticks command messes that up.  On the other 
hand, if I do the yticks command first, then I get the range I want, but 
the tick marks don't cover the whole range of the plot.

Is there a better way of doing this, or some way to fix the above method 
to make it work?
