Hello,
Using R 2.5.0 with PBSmapping package version 2.09:
When I try to read in a polygon shapefile (eight polygons, the file was
written by the
Feature Class to Shapefile command in ArcMap GIS 9.2) using the command:
importShapefile("TriCountyPolyDD")
The following error occurs:
Error in x[[jj]][iseq] <- vjj : incompatible types (from NULL to
integer) in subassignment type fix
Using read.shape on the same file yields
> TriCounty <-read.shape("TriCountyPolyDD.shp")
Shapefile type: Polygon, (5), # of Shapes: 8
>
Yet I wish to work with this shapefile using the PBSmapping tools.
Has anyone else encountered and/or repaired this?
Plan B would be to convert the Map object TriCounty into
a PolySet or PolyData used by PBSmapping package, but
so far I have not worked this out. Any suggestions?
Thanks, Rick Reeves
