[R] Save and load workspace in R: strange error.

[Hongxiao Zhu]

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.
