Re: [R] checkpointing

Those are good points, Duncan. I am experimenting with a nice checkpointing tool called DMTCP. It operates on the system level but is quite OS-dependent. It can be found at http://dmtcp.sourceforge.net/index.html. Still, it would be nice to be able to checkpoint calls within R to potentially l
