[R-sig-eco] readOGR and Multiple incompatible geometries in rgdal

[Patrick Giraudoux]

Dear all,

I have to cope with a MapInfo file  (.TAB and associated files) with 
obviously muliple geometries in (e.g. points and lines) and readOGR 
(package: rgdal). When reading, I get the following error message:

readOGR(".","PacoursIKA")
Error in ogrInfo(dsn = dsn, layer = layer, encoding = encoding, use_iconv = use_iconv,  :
   Multiple incompatible geometries: wkbPoint:wkbLineString

Of course, the cause is obvious and I can manage reading the file from 
e.g. QGIS (a dialog box permits to select one of the two geometries) and 
then export to a single geometry shapefile. The latter can be read from 
R using readOGR.

However, I would like to know if there is a work around within rgdal (eg 
an extra argument in readOGR) that could make the job done within an R 
environment. The workhorse in QGIS is gdal as in rgdal, so suppose 
something may be possible.

Best,

Patrick
