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

Hi Rers,

I would like to use the BATCH mode to R automatically:
open 2 R sessions (ex. data1.Rdata, data2.Rdata),
produce some calculations (
),
save 2 sessions (sol1.Rdata, sol2.Rdata),

My problem when using R CMD BATCH master.R is that when I use master.R  
as a master file, with:
   source(?file1.R?)
   source(?file2.R?)

with ?file1.R? script:
   load(?data1.Rdata?)
   

   save.image(?sol1.Rdata?)

and ?file2.R? script with
   load(?data2.Rdata?)
   

   save.image(?sol2.Rdata?)

sol.2.Rdata comes with information of sol1.Rdata, appearing that the  
1st R session did not shutdown.
Any suggestions to save sol1.Rdata and sol2.Rdata, independently from  
each other?

Grateful in advance,
All the best,

Diogo Alagador

You need to delete all the files initially loaded in data1.Rdata using rm()
eg rm(list=ls(pat=".*"))
