main.JobBatch: Static method to be called from the command line

In R.batch: Methods to run batch jobs in R

Description

Static method to be called from the command line. When called, this method will process one available job and return.

The following R command line options are recognized:

• --root=<path> or --root <path> specifies the root path of the batch directory.

• --reset specifies if each job should be reset before it is started.

• --sink specifies if each job output should be sinked to file.

• --details specifies if extra information should be printed to the standard output.

• --maxJobs specifies the maximum number of jobs this batch dispatcher should process before quiting. If -1, it runs until no more jobs are found. If Inf, it runs forever until being interrupted.

• --sleepTime specifies the number of seconds for R to sleep before checking for new jobs, when no more jobs are available. Only effective if --maxJobs=Inf.

• --clean specifies if all job specific created in the output path should be moved to the job path when job is done.

To avoid warning about unknown options when R, add these options at end after --args. See example below.

To run this from the command line, see 1. Useful scripts.
