Hi all,
I'm quite new to wireframe, essentially what I want to do is display a graph,
and z-values > 1 would be yellow and those < 1 would be blue.
This is a bit of my data.
0.334643563 0.350913807 0.383652307
0.370325283 0.38779016 0.42387392
0.39861579 0.418389687 0.460692165
0.43888516 0.468015843 0.520560489
0.499544084 0.535099422 0.60982153
0.569888047 0.634351734 0.717646392
0.717202578 0.810887467 0.935152498
0.901982916 1.044895388 1.228306176
1.12856184 1.314210456 1.462055626
1.377314404 1.540372345 1.6206216
1.494044604 1.618244219 1.631295797
data.m = as.matrix(read.table("/Users/James/Desktop/c.txt", sep='\t'))
library(lattice)
wireframe(data.m,aspect = c(0.3), shade=TRUE, screen = list(z = 0, x = -45),
light.source = c(0,0,10), distance = 0.2)
i know I probably need to use the col.regions or level.colors argument, but I'm
not sure what I actually need to supply to the arguments to get it to work. All
the examples I've seen also have a gradient of color between two or more
colors, I want to color half the graph with z values > 1 yellow, and <1 blue.
Thanks for any help. James
