reading a feature class

Hi Michael,



It worked partially.

I still have an error message

dd<-ogrListLayers(dsn="C:/sophie/Allpoints/All_poly.gdb")

bb<-readOGR(dsn=dd,layer="All_lays1")

Error in ogrInfo(dsn = dsn, layer = layer, encoding = encoding, use_iconv
= use_iconv) :

  Cannot open file

In addition: Warning messages:

1: In if (nchar(dsn) == 0) stop("empty name") :

  the condition has length > 1 and only the first element will be used

2: In if (nchar(dsn) == 0) stop("empty name") :

  the condition has length > 1 and only the first element will be used

Try

ogrListLayers( dsn="C:/sophie/Allpoints/All_poly.gdb")

that should give you the right layer name/s for use with readOGR

Dear Frede,



Thanks for your reply.



This is the function that is not working

bb<-readOGR(dsn="C:/sophie/Allpoints/All_poly.gdb",layer="All_lays1")



All lays is a feature class in a file gdb(new) .

The file is not corrupted I?m able to open it on ARCIS and I?m doing the
zonal statisctics there.

I opened the rgdal library and I?m using R studio

Rgdal version 0.8-16

Hi



I don't know the gdb file format. Is it in raster or vector format?



Since you used readOGR you probably did have a look at



http://www.gdal.org/ogr_formats.html



before asking.



So there, two ESRI formats are mentioned: personal gdb (old) and file gdb
(new?).



Do you what kind of gdb file you have?



Why you can't read the file could be because of several problems.



Is the file corrupted?



What is your OS?



What version of R/rgdal?



Does the OS/R/rgdal combination involves formats for either pgdb or
filegdb?



Nobody can help you with that little information you have given us.

Dear All,



I ?m trying ti import a feature class from a gdb to R using readOGR.

Unfortunately it is not working.

Anybody has a suggestion of a function to read it.
