Description Usage Arguments Details

Add/remove a cronjob to automate an R script to your personal crontab

addCronjob(name, desc = NULL, env_vars, scheduled_time, script_path,
  overwrite = FALSE, verbose = FALSE, warn = FALSE, bashrc = TRUE,
  logLevel = "info", textLevel = "none")

cronjobExists(name)

deleteCronjob(name)

`name`	A unique name for this cronjob
`desc`	A description of what the script does
`env_vars`	A list of environment variables that need to be set for this cronjob
`scheduled_time`	A list or string describing when the task should be run.
`script_path`	The filepath to the script you want to automate
`overwrite`	If the cronjob already exists, should it be overwritten?
`verbose`	Should extra messages be displayed while the cronjob is being built?
`warn`	Should errors stop the function or just give an warning?
`bashrc`	Should the user's .bashrc file be loaded before running the script?
`logLevel`	What is the minimum message level that should be logged?
`textLevel`	What is the minimul message level that should be texted, if texting is enabled?

cron does not start a shell and therefore doesn't load environment variables that would normally get loaded. Use env.var to set variables that are needed by your script and/or set bashrc = TRUE to load the user's .bashrc file each time before the script is run.

scheduled_time should be either a named list containing any combination of minute (0-59), hour (0-23), day_of_month(1-31), month(1-12)(Jan-Dec), day_of_week(0-7)(Sun-Sat) or a properly formatted cron string For example, scheduled_time = list(minute=30, hour=7, day_of_week=2) would result in the task being scheduled for 7:30AM every Tuesday. scheduled_time = "30 7 * * 2" would accomplish the same thing.

script_path should point to the location of a script you wish to automate. The script will be copied to the .crontabR directory in your home directory. Additional code will be copied to the beginning and end of the script so that crontabR's logging functions will work. It is this modified copy of the script that will be run by crontabR.

cronjobExists reads your personal crontab to see if a cronjob of the given name has been added by crontabR.

deleteCronjob will remove the lines in your crontab associated with the named cronjob. It will also delete the script from the .crontabR directory.
