[R] RGDAL OGRwrite question

[Scott Duke-Sylvester]

In the example I gave, the "temp.shp", 'temp.bdf", etc ... do not
exist in the current working directory (".") before I call:
writeOGR(shape, '.', layer='temp', driver='ESRI Shapefile', verbose=TRUE)

I should have specified this. Also, the working directory permissions
are set to owner read/write/execute (unix: drwxr-xr-x).
