We are using R in our class. One student claims to
be receiving the message

"Fatal error: unable to restore saved data in .RData"
Well, throw my suggestion away.
I sometimes get such message when I save .RData with some nonstandard 
packages
loaded and trying to open R with those packages not loaded. Especially 
when I 

shall be
loaded and trying to open R with those packages not ***installed***. 
Especially when I
work on one machine then save data transfer them on other machine.

Then it is worth to rename .Rdata, open R, load packages and open 
renamed data.

No. Just install those packages in library directory which when loadind 
.Rdata R wants to open.

The student is working in a Windows environment with Vista
using the precompiled binary distribution (R-2.7.2).

After searching the R site and reading FAQs, I suggested
the student find .RData in the working directory and delete it.

The student claims this did not work so I recommended starting
R from a command line with the --no-restore option.

Has anyone had any experience with this? Does anyone know
what may be causing this? This is the first time I have
encountered this.
