Hello, I hope someone can advise me on how to get R running on my Windows PC
again. I uninstalled R2.8.1, and also the previous version 2.8 that were on my
hard drive. I reinstalled 2.8.1, but when I started the program, the message
below came up, and R shut down.
"Fatal error: unable to restore saved data in .Rdata"
I uninstalled and reinstalled 2.8.1, but same results. Then I uninstalled 2.8.1 and downloaded the 2.9 beta version. Still the same fatal error message.
Any advice on how I can rectify whatever I did to wreck R?
Probably your .Rdata file contains some objects that cannot be restored
in the newer version of R. Perhaps some S4 object that is no longer valid?
You could try to load the workspace with your old version of R again. Or
better, if you do not need the wrokspace, just delete the .Rdata file in
your working directory.
Best,
Uwe Ligges
thanks,
Paul

David, thank you for your helpful reply.
a) The sessionInfo goof is actually kind of enlightening. I'm
assuming that the purpose of adding the "()" symbols is to tell R
that sessionInfo is a function to be invoked, and leaving "()"
empty says to use default arguments?
Yes. Exactly.
b) In the R GUI, I end my session by using the menu File > Exit. A
dialog appears, asking, "Save workspace image?", and I choose Yes.
In fact, I just did it and got a message, never seen this one before
"Console not found. Error in structure(.External"dotTclObjv:,objv,
PACKAGE - "tcltk"), class = "tclObj"):[tcl]invalid command name ".
6.1".
I am not an expert in the Windows GUI, but as a former user of it, I
would wonder if my installation of tcltk had gotten corrupted and
would try to reinstall. Caveat: That advice could be worth what you
paid for it.
Closed that message, another similar message was behind it, but now
the command name was "17.1"
c) yes, agreed --- John Fox has been helpful to me a couple of
times. I like the R Commander (it automatically adds those pesky
details like () that elude me), but I can't go the CRAN to get
packages from it, so I end up back at the GUI to install a package.
John has told me that moving back and forth between the GUI and
Commander is not how Commander was intended to be used. Perhaps
this practice has led to some of the present confusions.
Let's say I save a script or history or similar file that I would
like to recall at a later time,
If I save the file using RCommander, should I only open the file
using R Commander? Ditto for R GUI? Regardless of which platform
I'm saving the files with, they seem to have some of the same
extensions, ".R", ".r", ".Rdata", etc.
I doubt that would be necessary, assuming the scripts do not have
function calls that depend on R Commander being around. Files with .r
extensions are just text files by another name.
I could not find a saveLog function with R-search restricted to
functions but did find it as an argument to RCmdr. IIRC, RCmdr uses
Tck/Tl extensively.

This is just two suggestions and a guess.
a) When you desire the information from sessionInfo ,you need to
type :
sessionInfo() # not sessionInfo
... results come from function calls and all you got was the
sessionInfo code produced by the implicit print function to which you
gave the argument sessionInfo.
b) Tell us exactly the methods you used to save "my script", "my
workspace", "etc"?
c) As a guess, you had the Zelig package loaded under R-Commander
yesterday but not today. The right person to ask this question of
might be one of those package maintainers. (John Fox is very good
about supporting R-Commander.)
