使用cron调度R脚本 [英] Schedule R script using cron

问题描述

我想使用cron安排我的R脚本，但它不工作。看来R不能在cron中找到包。任何人都可以帮助我？

 ＃source my profile 
。 /home/winie/.profile 
＃script.R将加载包
 R CMD BATCH /home/script.R 
  

解决方案

考虑这些提示

1. 使用Rscript（或littler）而不是 R CMD BATCH


<



2. 确保脚本自行运行

$ b $
b

3. 在详细模式中测试几次

a href =http://dirk.eddelbuettel.com/cranberries/> CRANberries 通过cronjob调用R脚本
（我通过littler ，但Rscript
也应该工作）。为此，我的Ubuntu服务器上 / etc / crontab 中的条目是

 ＃每几个小时，跑小红莓
 16 * / 3 * * * edd cd / home / edd / cranberries&& ./cranberries.r 
  

，因此每三个小时过去十六分钟，一个shell命令正在运行我的身份。它改变成工作目录，并调用R脚本（具有可执行模式等）。

看看这个，我实际上可以运行脚本，并且 setwd（）中的命令....

I am trying to schedule my R script using cron, but it is not working. It seems R can not find packages in cron. Anyone can help me? Thanks.

The following is my bash script

# source  my profile
. /home/winie/.profile
# script.R will load packages
R CMD BATCH /home/script.R 

解决方案

Consider these tips

1. Use Rscript (or littler) rather than R CMD BATCH

2. Make sure the cron job is running as you

3. Make sure the script runs by itself

4. Test it a few times in verbose mode

My box is running the somewhat visible CRANberries via a cronjob calling an R script (which I execute via littler but Rscript should work just as well). For this, the entry in /etc/crontab on my Ubuntu server is

# every few hours, run cranberries
16 */3 * * *    edd     cd /home/edd/cranberries && ./cranberries.r

so every sixteen minutes past every third hour, a shell command is being run with my id. It changes into the working directory, and call the R script (which has executable modes etc).

Looking at this, I could actually just run the script and have setwd() command in it....
