Hi Everyone,
Sorry folks, my email program, Netscape Communicator, cannot send text
email correctly. So this attempt goes out in both html and text.
I have a nice solid SpatialPologonsDataFrame and a new line file
(wkbLineString) called "major roads.shp".
MY QUESTIONS. I would appreciate examples of
a)How to merge the intersection of a **SpatialPologonsDataFrame and a
wkbLineString
b)How to plot the result.
c)How to display the street name on the plot (that's FNAME from the
major roads.dbf file).
ADDITIONAL INFORMATION.
The SpatialPologonsDataFrame is a garden variety collection of
geographical polygons.
> tx1_sp <- readShapePoly("precinct08.shp", IDvar="PCT",
proj4string=CRS("+proj=aea +ellps=GRS80 +datum=WGS84"))
The new file to intersect merge is major roads line map that should
overlay part of my SpatialPolygons. It does not behave like a Shapfile.
>main_roads <-readOGR("main roads.shp", layer = "main roads")
OGR data source with driver: ESRI Shapefile
Source: "main roads.shp", layer: "main roads"
with 29161 rows and 33 columns
Feature type: wkbLineString with 2 dimensions
Thanks yet again,
Jim Burke
