Save and load workspace in R: strange error.

Hi,

I finally figured out where the problem is. It was because the 
user account has a 10GB quota for the systerm that I used.
Once the space limit is reached, R will have this error whenever you
want to save or load.
Gosh! It took me so long to realize this.

Did you check whether 'junk4.RData' was created and what its length was - 
maybe an empty file is being created.  Is there some sort of quota or 
permissions problem?  My suggestion would be to look at the size and 
permissions on the directory and the file.  If you need more help, I
would 
suggest posting more details back to the list, e.g., what OS you are
using, 
and a directory listing that shows file sizes and permissions (i.e., as
you 
get with 'ls -l' on Unix systems.)

Hi,

I tried to load a .RData object on unix system using R, it gives error:

Error: restore file may be empty -- no data loaded
In addition: Warning message:
file 'junk3.RData' has magic number ''
    Use of save versions prior to 2 is deprecated

This happens only for using MY user account for the Unix system. I tried 
to use a friends's user account to load the same data object, it is
fine. And it never happened to me before until sometime last week.
And This error happens even when I generate a simple random number
from my user account and save it, and load it again.(So obviously it is 
not a R version mismatch problem). Does anybody know what happened?

Here is an example what happened:

x=rnorm(100)
save.image('junk4.RData')
load('junk4.RData')

Error: restore file may be empty -- no data loaded
In addition: Warning message:
file 'junk4.RData' has magic number ''
    Use of save versions prior to 2 is deprecated

Thanks for any suggestion.

Hongxiao
