On the basic RInterpreter notebook, the first paragraph fails with:
> could not find function "repr"
The following paragraph hits "knit" and fails with
org.apache.zeppelin.rinterpreter.rscala.RException
at the .sparkREnv directive.
What assumptions/prerequisites is it looking for in the installation?
