[R-sig-Geo] Displaying CIR images and overlay shape files

[Edzer Pebesma]

A familiar problem. This works (for S3 methods at least):

 > library(sp)
 > methods(image)
[1] image.default                 image.SpatialGridDataFrame*
[3] image.SpatialPixelsDataFrame*

   Non-visible functions are asterisked
 > ?image.SpatialGridDataFrame
