Dear r-sig-geo,
I am in a bit of a bind. I am trying to write a shape file using
writeOGR() in rgdal. I just realized that I may have too many characters
in the cells as they are getting cut off when the shape file is created.
The cells are unchanged in the SpatialPointsDataFrame. But when I
inspect the .dbf they are all truncated. The cells that are cut off
contain literature citations, so some are very long (hundreds of
characters). Is there a solution to this problem? This shape file is
being imported into Geoserver so I am some what limited as to the
formats that I can use.
The OGR driver truncates (I think to 254 characters), so use
writeSpatialShape() in maptools instead, passing your large number through
the max_nchar= argument. Please read the details in ?write.dbf - field
widths above 254 are not portable.

Any advice?
Thanks in advance,
Michael
