I gave up saving workspaces a while back. I prefer to have everything as
a script (or scripts) that I can re-run, describing the analysis from
data processing to results. Most of the work I do doesn't involve the
huge data sets that some list members work does, so I can usually re-run
the scripts from scratch and continue where I left off.

If I have complex or tedious data manipulation scripts to process data
before analysis, or a computationally complex bit of analysis, I may opt
to save the resulting objects using save(), which I then load as
required using a load() call within my analysis script, rather than
re-run them each time.

I've been caught out a few times with things being loaded that I'd
forgotten about when I reused a workspace.

All the best,
