Dear All,    

  How can I define a color sequence for each image value? I have several images with values varying from 1 to 5, and I would like to assing a fixed color for each value (green for 1, yellow for 2...). I used somethink like:    

> image(img,col=c("green","yellow",...))
   

  but unfortunately whem I have absent values, the color that I defined for each values change.    

  Thanks a lot,

  PS : Merry Christmas!!!
