[Qgis-user] Problem with HomeRange plugin - rgdal dependencies

[John C. Tull]

I'm also on OS X using qgis built from the current svn trunk. I would  
run a quick test with a point file with 25 points and a single id  
variable (one individual home range to compute). After taking care of  
the rgdal dependency, I am now running into problems with the output  
of the computed shapefile while running the plugin. Here is the error  
I receive in a dialog window:

R error: Error in writeOGR(khr.polygons, dir, name, "ESRI Shapefile") :
GDAL Error 1: Failed to create file .shp file.

Any ideas on how to fix this?

Regards,
John
