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

是否可以从脚本中确定脚本是在 R-GUI 中运行(特别是 OS X 上的 R.app)还是从终端/命令行调用(即 R--vanilla -f script.R)?如果是这样，这怎么可能?

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?

我之所以这么问，是因为我有一个可以并行运行的脚本(使用 doMC 库)，不应在 GUI 中使用该脚本.有时我需要进一步处理脚本中计算出的数据，所以我想在这些场合从GUI调用脚本.

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.
