I am drawing level plots but I would like to specify the range of the colorkey,
I am not having any success figuring this out so any help would be greatly
appreciated!
Here is an example of what I am trying to do:
disp<-1
x <- seq(1, 10,by=1)
y <- seq(1,10,by=1)
g <- expand.grid(x = x, y = y)
g$z <- 1/exp((abs(g$x-5)+abs(g$y-5))*disp)
g$z<-g$z/sum(g$z)
levelplot(z ~ x * y, g,xlab="x co-ordinate", ylab="y co-ordinate"
,colorkey=TRUE,col.regions=(col=gray((0:32)/32)))
I would like to enforce the number of divisions on the colorkey scale and the
size – so for example from 0 to 0.1 in increments of 0.02 (just as an example).
I apologize if this is an obvious question but I have read the documentation
and scoured the archives and cannot figure it out.
