To troubleshoot this, start by checking if java is installed or not. Then check if JAVA_HOME variable is set or not by echo $JAVA_HOME .
If it returns nothing and java is installed, then do export $JAVA_HOME=/your/path .
Installation instructions are available here .

It's probably best to uninstall Java.
Then download and install a new version of Java this should set your JAVA_HOME .
Now try installing rJava.
