Method validate()

Validate the launcher.

NULL (invisibly). Throws an error if a field is invalid.

---

Method script()

Generate the job script.

Usage

Arguments

name

Character of length 1, name of the job. For inspection purposes, you can supply a mock job name.

Details

Includes everything except the worker-instance-specific job name and the worker-instance-specific call to crew::crew_worker(), both of which get inserted at the bottom of the script at launch time.

Returns

Character vector of the lines of the job script.

Examples

if (identical(Sys.getenv("CREW_EXAMPLES"), "true")) {
launcher <- crew_launcher_pbs(
  pbs_cores = 2,
  pbs_memory_gigabytes_required = 4
)
launcher$script(name = "my_job_name")
}
