R help - May 2010 - Fatal error that doesn't let me start R

Hi, all.

I have R installed in my computer.  I guess I did something in my previous
session, and now every time I start R, I find the following message:

"Fatal error: unable to restore saved data in .RData"

I uninstalled R and installed it again and I'm still getting this message.

Can anyone help me?

You likely have an object in the .RData file which can't be loaded, 
because it relies on a package you no longer have.  You can run R with 
the --vanilla command line option and it won't try to load .RData, then 
reinstall all of your packages, and that might fix things.  
Alternatively, just delete the .RData file, and the problem will go away 
(but so will your data.)

It looks like you have an .Rdata file that is corrupt -- you just have
to remove it.

When you quit R, you should have noticed a prompt that asks you if you
want to "Save workspace image". When answer "yes", it will
save your
workspace into an ".RData" file.

Anyway, it's not a problem with your R install, which is why
reinstalling R didn't work, you just have to remove this file. Without
any more details with respect to how you launched R, what type of cpu
you have, etc., my first guess would be that this file resides in your
home directory.
