  I explained this to you yesterday, but your email address was 
different. So far I've seen you use three different email addresses! If 
you keep to one email then life will be much simpler!

  The polymap() function call here is wrong - it is used to draw a 
polygon. Just remove it and do:

  grid.pts <- gridpts(bbox(pts),10*np)

  this produces a grid of 10*np points in the bounding box of the points 
in pts. You can then use polymap() to see them:
