R脚本的Cron作业失败 [英] Cron job for an R script failing

问题描述

我的R脚本在单独运行时可以按预期工作，但是当我尝试将其作为cron作业运行时，它总是会失败

My R script works as intended when I run it on its own, but when I try to run it as a cron job, it keeps failing saying

Error: RStudio not running
Execution halted 

cron作业的日志文件。

推荐答案

听起来像您正在尝试做只能在RStudio中运行的操作。也许您中的一个功能试图调用只能在RStudio中运行的功能，例如此处？

Sounds like you are trying to do something that can only be run in RStudio. Maybe one of you functions is trying to call a fucntion that can only be run in RStudio, for example one of the functions from here?

在这种情况下，如建议在这里，您可以根据脚本是否在Rstudio中运行来确定其行为。可以通过下一行：

In that case, as suggested here, you can make the behavior of your script dependent on whether it's run in Rstudio or not. That can be achieved with the following line:

isRStudio <- Sys.getenv("RSTUDIO") == "1"
