Tony, Thanks for return. Actually, the data object 'junk4.RData' was created but have size 0. It seems no data was saved. But the real data that I want to load have data in it, which I can't load use my own user account. But if using other people's user account under the same system, it can be loaded.
All the files has the following property if I use ls -l: -rw-r--r-- The OS I used is windows xp. But I use SSH to connect to the unix server. I have been using this server for a long time, this error happened since some day and from then on, I can never load/save workspace.
