[ilai]

Try to plot the points first followed by vis.gam(...,type='contour',
color='bw', add=T) instead of vis.gam followed by points.

These point are plotted on top of the contours so that some of the contour lines are only partially visible.  Is there a way to make the contour lines fully visible?  I cannot reverse the order and plot the points first and then call vis.gam().  Or, can I?  Are there other options?
