I have a dataset which uses a custom projection, and I would like to
import shape files to add maps to the plots. I was able to import the
shape file using maptools as both a SpatialLine, and SpatialPolygon,
however I'm not sure how I can modify the coordinates to my custom map
projection. I have converted the standard R maps to my map projection,
but the spatial objects are a little out of my understanding, as I am
not sure how to get the coordinate values out of and then back into the
spatial objects.
Does anyone know how I might be able to modify the coordinates of the
spatial objects to my projection.
Thanks,
