R help - May 2009 - How to save independent R sessions in BATCH mode???

Hi guys,

I already have put this question some time ago however replies were  
not straight to the problem. Even so thanks a lot for the answers!

I reformulate the problem.

I have a script file with the following commands:

for (i in 1:300)
- open session --> load(?X_i.rdata?)
- perform some calcules --> (
)
- save session --> save.image(?Y_i.rdata?)
end for

The problem here is that, I cannot save.image and begin a new ?clean?  
session. An hypothesis could be to delete all R objects after the  
save.image, but this does not seem too efficient to perform.
What should I do to begin a R clean session in the same batch  
processing? Are there any other suggestion on this?

Thanks in advance,

Diogo Andr? Alagador

Put it into a function. That function accepts the objects you have had 
in X_i.rdata as arguments and that returns the objects you are gping to 
savein Y_i.rdata.

Then you do not need to clean up/load/save all the time anymore.
