How to run R codes inside a shell script?

Question

I have an R file (myfile.R). I want to run it using a shell script. How can i do this? I tried this:

#! /bin/bash
Rscript myfile.R

but it gives me this error: rscript: command not found

I also tried this:

#! /bin/bash
R --not-save-- < myfile.R 

It also gives this error: R: command not found

What is the best way to do this?

Answer 1

The idea is not to write a shell, but to write an R script. This is for Rscript, and our littler package offered /usr/bin/reven before that.

So just

 #!/usr/bin/Rscript

 cat("Hello, world\n")
 # rest of your code below 

or use

 #!/usr/bin/r

for littler - I have several cron jobs that do just that.
