Shell bash script does not run R

I have an R script that I can run with 

R CMD BATCH Rtest.R a.txt

and it successfully returns the results to a.txt. I am attempting to write a new shell script that plan to run daily, and have made the following script, called morning

#!/bin/bash
sh R CMD BATCH Rtest.R a.txt
cat a.txt >> predicted.txt

I run this with the following commands

chmod 755 morning
./morning

I can get this to work sort of, but end up with the error

sh: 0: Can't open R

and execution halts midway through. When I run it with a different command (such as echo alpha > a.txt) it works as expected.

I am working under Ubuntu 14.04

In your morning file. Please also check if R is in the PATH.

#!/bin/bash

R CMD BATCH Rtest.R a.txt
cat a.txt >> predicted.txt
