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.
try: col = rev(tim.colors(100)) In addition, consider using the spatial classes provided by the sp-package to plot your data. See [1] for some examples of spatial plot. cheers, Paul [1] http://wiki.r-project.org/rwiki/doku.php?id=tips:spatial-data:spatial_data_visualization
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
