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!
