R distinguishing between batch and interactive mode

问题

I would like to have a condition in my code which allows me to distinguish if the code is running in Batch or interactive mode (via console). It would be something like this:

if (interactive mode) {do this} else if (Batch mode) {do that}

Is there a way to achieve this? Thanks for your help.

You can use the interactive function. For example, executing this from a terminal

Rscript -e 'cat(interactive())'

returned FALSE for me, while executing interactive() from my RStudio session returned TRUE.
