[R-sig-Geo] Tweak legend in image.plot()

Hi all,

I've plotted my data using;
 > image.plot(data, zlim=c(0,800), add=FALSE, nlevel=100, horizontal=T, 
legend.shrink=0.5, legend.width=.8, col=tim.colors(100))

 From here, I'd like to make adjustments to the legend like;

1. Reversing the scale.
For example, the legend plots zlim as 0= blue to 800=red. Since I'm 
dealing with rainfall data, it's more visually logical to express 
highest precipitation as blue. Hence 0 = red to 800 = blue would be desired.

2. Shifting the legend up by 2inches from the bottom of the page

3. Changing the legend's font size/type.

Does anyone have any suggestions?



Muhammad
