Hello All,    

  I've problems to interpret the contourplot for a binary response dependent variable. For example, I ploted the survived probability for the titanic3 dataset,    

  http://www.geocities.com/useebi/data/CondenContour.jpeg    

  Trellis displayed two panels of contour, one for dead and one for alive. However, the contours between the two panels didn't conform to the rule of prob(dead) = 1 - prob(alive). How I should read the contours? What I did wrongly? Is there an example that I could follow?    

  Thanks!
