Not on my computer.
Hmmmm. Why do these always happen to ***me*** and only to me?
I get TRUE twice whether at start up, source()ing .Rprofile, or C-c C-n'ing
the lines from emacs ESS.
I have to type
load(".RData")
_after_ startup to get behavior like you describe.
Perhaps, you have something later in your .Rprofile that specifically
load()'s your old .RData?
No I haven't. And that couldn't be the case, since ``Junk'' is
there
(it wasn't there in the saved image).
So it would seem that what is happening is that the saved .RData is
being loaded or restored
***after*** the commands to read in .Random.seed (and Junk) are
issued. The .Random.seed
in the saved image then overwrites the .Random.seed that was just
read in.
But why does this happen on *my* system, and not on Chuck's???
Because I goofed by rerunning ALL the lines in .Rprofile rather than
just the last two. When I run just the last two, I get the behavior you
describe.
Sorry for the misdirection.
