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. -Don At 1:59 PM -0600 12/29/05, Charlotte Reemts wrote:
Dear R users, I am using spatstat to analyze point patterns (tree locations). I would like to import the shapefile with the study area polygons (six total) into R and use it to create the window for the spatstat analysis. I do not simply want to use a rectangle because the study areas spread out over 40000 ha. Any suggestions would be greatly appreciated.
