R区分批处理和交互模式

问题描述

我想在我的代码中有一个条件，该条件使我可以区分代码是在批处理模式下还是在交互模式下(通过控制台)运行.会是这样的:

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}

有没有办法做到这一点?感谢您的帮助.

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

推荐答案

您可以使用interactive函数.例如，从终端

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

Rscript -e 'cat(interactive())'

为我返回了FALSE，而在我的RStudio会话中执行interactive()时返回了TRUE.

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