R脚本的Cron作业失败

Question

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 

This is the log file for the cron job.

Loading required package: methods

The following object is masked from ‘package:base’:

    date

This is my cron job set up

## cronR job

Answer 1

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 ?

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"

Hope this helps.
