Shiny script from Ubuntu bash

Question

I wanted to run with crontab (the system daemon used to execute desired tasks at certain times) a shiny script.

I first tried running sh Autorun.sh, being in the file:

R
shiny::runApp(...)

but that didn't work

I also tried writting directly Rscript shiny::runApp(...) but it also doesn't work

Any ideas?

Try R -e 'shiny::runApp(...)'. You might need to switch quotes if you're using any inside runApp(). — Molx, Commented Jun 1, 2015 at 12:24

To run code using R on shell, you must use the -e option, which stands for expression. The same thing can be done via Rscript.

The correct syntax is then:

R -e 'shiny::runApp(...)'

Care must be taken with the quotes if there are any in the expression being used.

For more information on other command-line options, check An Introduction to R - Appendix B.
