Dear friends,
The following is an example to explain my question. I want to get a
legend which will show the z-values according to different colors in image()
function.
x<-sort(runif(10)) #x-coordinates
y<-sort(runif(10)) #y-coordinates
z<-matrix(runif(100),nrow=10) #attributes values
image(x,y,z,col=gray((6:3)/6))
# legend(x,y,legend=z,col=gray((6:3)/6)) #error. the colors should denote
different z-values, i want to get this legend.
Thanks.
