[R] Request for help re. opening workspace

[Prof Brian Ripley]

This is I assume Windows?  If your version of Windows has the /3GB switch 
set, try starting with

Rgui --max-mem-size=2.5G

(if not, that will probably not work) and see if the workspace will load 
(slowly).

Saved workspaces are compressed, often highly compressed.

I have to say I am pretty unsure about this, as you appear to have saved a 
2023kb vector and how you manage to create that is unclear: perhaps you 
used memory.limit?
