[R] Fatal error: unable to restore saved data in .Rdata

[Susan Yeh]

Dear Sir/Madam:
I'm currently running R 1.9.1 on a Mac OS 10.3. I have been able to
use it fine for a while now. But for some reason, it now crashes
each time I open it with the error: Fatal error: unable to restore
saved data in .Rdata
I read on the online help forum that I can just delete the bad
.Rdata file. But I cannot find it. I even tried to delete
everything related to R and reinstalling but the problem has not
gone away.
Please HELP!
Thank you,
Susan Yeh
