plotting a grid with color on a map
Thanks, Jim. This seems to be what I am looking for. Just have to fine tune the colors to get some distinctive greens, blues, yellows and oranges in there and I should be good to go.

It was the NAs that fooled color2D.matplot. This gets your colors,
although not exactly what you want. Look at the help for color2D.matplot
to get that. I think fiddling with the x and y limits on the map() call
will get the positions right.
temp1<-read.table("time1test.dat",header=TRUE)
library(plotrix)
# reverse the row order, as color2D.matplot reverses it
color2D.matplot(temp1[36:1,],c(0.5,1),c(0.5,0),c(1,0),axes=FALSE)
# don't erase the above plot
par(new=TRUE)
# do a "ghost" plot with just the axes
plot(0,xlim=maplim[1:2],ylim=maplim[3:4],type="n")
# add the map on top in black
map(add=TRUE,col="black")
