[R] importing shapefiles into spatstat

[Don MacQueen]

Go to CRAN, to the "Packages" page, do a simple search on the text "shape".
It will quickly lead you to
   maptools	tools for reading and handling shapefiles
 From there, I guess you'll have to extract the polygons from the 
structure that is returned by the function(s) in the maptools package.
