Dear all
I am having problems when reading shapefiles using readOGR with the
rgdal package. I have read several times these files in the past without
any problem. Since a few days, while I apparently did not change
anything (no update, similar version of R, same shapefiles), I always
have this error with the following statement:
> sol <- readOGR(dsn = ".", "sol")
>> Erreur dans ogrInfo(dsn = dsn, layer = layer,
input_field_name_encoding = input_field_name_encoding) :
>> GDAL Error 4: Record count in .shp header is -3, which seems
unreasonable. Assuming header is corrupt.
This error initially occurred with version 2.11.0 of R. I uninstalled R,
installed the version 2.12.0 for Windows, I updated all the packages,
but the trouble persists. The same files can be read on other computers
of my colleagues, whatever the version of R and rgdal.
How can I solve this? Many thanks in advance.
Antoine
