How to run an R script in crontab

Question

Using crontab -e I\'ve tried:

* * * * *  Rscript /home/.../file.r
* * * * * /usr/lib/R/bin/Rscript /home/.../file.r
* * * * * /usr/bin/Rscript /home/.../file         


        

Answer 1

in my user level crontab I run a R script to collect tweets from various sources.

I used: crontab -u myusername -e added this to the end of my crontab file

0 0 * * * /home/bob/Documents/SWtweets/tweetbash.sh

I ran it as a user vs root, don't what difference it makes, but it only worked for me when I ran it at user level.

below is what I put in my tweetbash.sh shell script, which tells the bash program to run the R script located at the path indicated.

#! /bin/bash R CMD BATCH /home/bob/Documents/SWtweets/tweets.R

did chmod +x tweetbash.sh

it works for my purposes.
