Schedule multiple R scripts to run sequentially

Question

I have multiple scripts naming R001.r, R002.r, and so on. I need to schedule them so that they run in a sequential manner one after the other. What would be the best approach to do this.

Answer 1

I think you want to wrap your r scripts in a caller sh file and then invoke it through terminal. Here is what I would do.

1. Open up a terminal or any text editor available and fill it up with the following commands:

   Rscript R0001.r
   Rscript R0002.r
   Rscript R0003.r
   ...

Save this file into something like call_my_scripts. You can then execute it via standard unix shell commands as follows:

./call_my_scripts

This will run sequentially by definition. Make sure you give exec permissions to the file before you invoke it as follows:

chmod u+x call_my_scripts
