[R-sig-Geo] How to extract coordinates values from a shapefile?
I'm not sure if this is what you want. But the function coordinates() in sp
package gives you the coordinates of SpatialObjects.
Regards.

Issues with unionSpatialPolygons on Ubuntu
Hi,
I've cross posted with r-sig-debian since they may be an issue for
linux (never had this problem on my windows machine...)
I recently made the switch to Ubuntu 10.04 (lucid), and found that
unionSpatialPolygons() gives me the following error when trying to
combine polygons within a shapefile:

maptools no such file
Hello,
I'm having problems reading a shapefile with read.shape (maptools). I'm absolutely sure my file is there, but I get "no such file". The wd is ok, since read.table for example does find the file.

Gracias Beatriz, efectivamente, lo que indicas en tu ejemplo es lo que obtengo al final de mi proceso.
En todo caso pruebo tu opción con mis datos, si es como imagino seguro que es más rápida de montar y más elegante que tratar el resultado de un sink() (recuerdo que en su momento lo intenté con fotify pero no supe bien como atacarlo, no conocía el enlace que me mandas, por tanto lo pruebo de

map data.frame() data after having linked them to a read.shape() object
Dear all,
I try to first link data in a data.frame() to a (polygon) read.shape()
object and then to plot a polygon map showing the data in the
data.frame. The first linking is called "link" in ArcView and "relate"
in ArcMap. I use the code shown below, though without success.
Help with this would be greatly appreciated.
Thanks!

writing polygons/segments to shapefiles (.shp) or other ArCGIS compatible file
I am not sure a previous e-mail reached the list (no mail aknowledgement from R-boundle etc.). The question was how to write polygon

the documentation is a bit beyond of my mind.... and I cannot get the meaning of the functions write**** and its application to the
