[R-sig-Geo] Fwd: Re: Conversion of a SpatialPolygonsDataFrame into a ESRI file

[Joona Lehtomäki]

Hi Cristina,

Which version of ArcGIS are you using? The dbf-format is notorious for 
mangling the field names longer than 10 characters. I can't imagine how 
this might prevent the attribute table from showing, but you never know.

In ArcGIS, you could just try exporting the shapefile into a new file 
(shapefile or geodatabase feature layer) and see if the new file behaves 
better.
