Not completely, as I started two topics in one thread. The first one,
interfacing ArcGIS personal geodatabases through rgdal (OGR drivers) has
been dealt with here:

https://stat.ethz.ch/pipermail/r-sig-geo/2009-June/005889.html

and more recently with the closed source ArcGIS 10.0 API here:

https://stat.ethz.ch/pipermail/r-sig-geo/2012-January/014090.html

followed by:

https://stat.ethz.ch/pipermail/r-sig-geo/2012-February/014094.html

and follow-ups would be easier findable when added to that thread.

The second topic addressed dealing with space-time features between R
and ArcGIS, for which rgdal/OGR could not be a solution, AFAICS.
