[R] How to protect two jobs running on the same directory at the same time not to corrupt each other results:

[Patrick Burns]

You can 'save' the objects produced by each BATCH
job in a file whose name relates to the job.  With this
technique, you can run as many BATCH jobs on the same
data as you like.

Once the jobs are done, then you can 'load' the files that
were saved.
