I haven't used this myself, but Gnu Screen is designed to offer just
this sort of functionality.

On the other hand, re-connecting to a running computation doesn't really
get you much: you can check that it's still running, but if it is you
can't do anything in the session until it's done anyways. As an
alternative, when I'm running long simulations on a remote machine I
include code to email me progress reports so I know when runs are
starting or finishing.

Our network uses shell scripts to process R batch jobs, so it's easy to
add these little email notes. Presumably you could do the same from
within R itself, via the system() function.

Cheers,

Tyler
