cron_rm: Remove a cronjob
In kevinushey/cronR: A package for interacting with cron jobs from R.

Use this command to remove a cron job added by cron_add.

1	cron_rm(id, dry_run = FALSE, user = "")

`id`	A set of ids, partially matched from the beginning, we wish to remove. We only remove the id if it is uniquely matched in the file.
`dry_run`	Boolean; if `TRUE` we do not submit the cron job; instead we return the parsed text that would be submitted as a cron job.
`user`	The user whose crontab we will be modifying.
