R脚本：确定脚本是在GUI中运行还是从命令行运行 [英] R Script: Determine whether the script is run in the GUI or from command line

问题描述

可以从脚本中确定脚本是否在R-GUI（特别是OS X上的R.app）上运行，或者是否已从终端/命令行调用（即 R --vanilla -f script.R ）？

我问的是因为我有一个脚本可以并行运行（使用 doMC library），不应该从GUI中使用。有时我需要进一步处理在脚本中计算的数据，所以我想在这些情况下从GUI调用脚本。

解决方案

也许你正在寻找 interactive（）？

Is it possible to determine - from within the script - whether the script is running in the R-GUI (specifically R.app on OS X) or whether it has been called from Terminal/command line (i.e. R --vanilla -f script.R)? If so, how is this possible?

I'm asking because I have a script that can run parallelized (using the doMC library), which should not be used from the GUI. Sometimes I need to further process the data calculated in the script, so I'd like to call the script from the GUI on these occasions.

解决方案

Perhaps you are looking for interactive()?
