R help - Nov 2007 - How can I read the actual value (?) defined by set.seed(?) earlier?

Hi all
 
I need to get the seed value that has been set by set.seed() earlier. I
only do have the workfile *.Rdata so I can not simply look to the code.

Thanx for any help, J

You cannot: it is not stored at the time.  set.seed() sets .Random.seed, 
and you can save/restore that.  However, the workspace will only contain 
the current value, not the initial value.

Normally the history is saved when you save the workspace: perhaps you do 
still have that and can search it for your call to set.seed (if there is 
one: there need not be).
