[R-sig-Geo] to many characters in .dbf file?

A shapefile limits the width of a character field to 254 characters: http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?TopicName=Geoprocessing%20considerations%20for%20shapefile%20output. Perhaps you will need to export your long field into a different format.

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
This shape file is being imported into Geoserver so I am some what
limited as to the formats that I can use.

Any advice?

Thanks in advance,

Michael Denslow
