Hi,

if I try to save (via save(...), write.table(...), etc.) some data on a full (!)
disc (free disc space was ~ 20Kb) the save command seems to finish without an
error. However, if you try to load the saved file to R again different errors
(depending on the load routine) occur. I think it would be very helpful for
useRs if an error is returned if the disc is full (similar to the error if the
user has no write permission).
