Hi everybody,
I have a SpatialLines object that I created by using the gBoundary()
function on a SpatialPolygons object. I've attached a plot ("SpatialLines
Segmentation.png") of the SpatialLines object to this email. What I would
like to do, is segment these SpatialLines wherever there is an in
Thanks Roger. This does exactly what I want, and also gives me an

the bounding boxes of other polygons from a SpatialPolygonsDataFrame. I am
having a number of errors right now, which I am unsure how to fix. My code
is basically as follows:
temp = bbox(spdf_u[1,])
temp =
Hi everybody,

simple polygons that overlap so I could see how the functio
