To all,
Currently, I have old datasets(shapefiles) that contain a plant code #
field in the attributes table. I have successfully merged in a table
with spp. names to correspond with the plant code #'s. During this
process my attribute data is resorted and I lose continuity with other
attribute data. (I'm using the (sp) and (maptools) libraries to
execute read/write Poly/Point shape functions.) While merging, how do
you maintain continuity between all of the other fields in your
attributes table?
Thank-you for your time and help,
Levi
