Dear list members,
I have been trying to import a shapefile, but I am facing the following
problem:
> readOGR('.','SOU-0')
Error en ogrInfo(dsn = dsn, layer = layer, input_field_name_encoding =
input_field_name_encoding) :
Multiple # dimensions: 2:1364727026
> ogrInfo('.','SOU-0')
Error en ogrInfo(".", "SOU-0") : Multiple # dimensions: 2:21374114
The problem seems to be with:
> ogrFIDs('.','SOU-0')
[1] 0 1 2 3 4 5
6 7 8 9
[...snipped content...]
[81] 80 81 82 21374112
I don't know why, but an integer seems to be imported as if it were
double (or something like that!)
If I open the dbf file and save it (with e.g. MS Excel) as a dbase IV
file, then it works. However, when I have to do this repeatedly it can
be really annoying. Is there any way to overcome it? It is a documented
issue (if so, excuse me)?
Thank you very much for any help that you can offer.
José M.
