memory accumulation

["Crawford.Winnie" <crawford.winnie@ensco.com>]

All,

 

S-Plus 8 on Windows XP

 

I am running into a memory problem with a script. After running it 3 or 4 times, I get an error that there is not enough dynamic memory. I checked the help and found the memory.size() function, so I ran it at the beginning of the S-Plus session and after every script run. Upon opening S-Plus, I get a value of 7541984. After each run, I got the following:

 

8936128

9173952

9569904

9867680

 

The last value was after the script crashed. When I tried to open the Language Reference, S-Plus crashed. I opened it again and looked up options().  Under memory, it says:

 

memory

the maximum size (in bytes) for all in-memory data. If this limit is exceeded, the session is terminated to avoid runaway computations that may slow down or crash the computing system. You may want to check for memory growth by calling the function memory.size ; if things get out of hand, quit and re-invoke S-PLUS.

 

The last sentence surprised me. I thought there would be a function to clean up the memory. It seems like quitting and re-invoking S-Plus is a little harsh. Has anyone figured out a way to scrub the memory accumulation? Thanks for any help you can provide.

 

Win
