Hi all,
I hope someone can help me with this.
Given,
library(fields)
x <- array(rnorm(100),dim=c(50,50))
image.plot(x)
I want to change the range in the color bar so that the range is from -1
to 1. I did adjust the image.plot() command to
image.plot(x,zlim=c(-1,1))
but the image shows white spaces.
How can I set the the color scale such that values which are less than
- 1 are assigned a color e.g. blue and those which are more than 1 are
assigned red.
In essence, how do I make the color scale to reflect the a certain band
of values i.e.
color 1 = > 1
color 2 = 0.9 to 1
color 3 = 0.8 to 0.9
...
color 8 = -0.8 to -0.9
color 9 = -0.9 to -1
color 10 = < -1
