In order to automate a shiny data reload, you will need to use the “cron” package. This package will allow you to schedule when the data should be reloaded. You can either use the “crontab” command or the “crontab2” command to do this.
The “crontab” command will allow you to schedule the data reload for every minute, hour, day, week, month, or year. For example, to schedule the data reload for every minute, you would use the following command:
crontab -e
*/1 * * * * Rscript /path/to/script.R
This would reload the data every minute.
The “crontab2” command will allow you to schedule the data reload for every 2, 3, 4, 6, 8, or 12 hours. For example, to schedule the data reload for every 2 hours, you would use the following command:
crontab2 -e
*/2 * * * * Rscript /path/to/script.R
This would reload the data every 2 hours.
