Dear R colleagues,
Does anyone know if it's possible to create a vector with coordinate values
extracted from a shape loaded with readShapePoly command of "maptools" package?
For example, the following code loads the shapefile containing Brazilian
states division:
library(maptools)br<-readShapePoly("BR-map/3.shp")
What I need to do is create a vector which contains all lat and lon values
inside this shapefile...
Thanks in advance,
Thiago Veloso.
