Call notebook using R in Databricks

I have a R notebook in Databricks, that I want to call inside an other R notebook.

I know that to call the notebook_a, one should do :

%run /path/notebook_a

But I want to do it inside an R script. For example :

if(condition){ %run /path/notebook_a }

Of course this code does not work.

Thanks a lot.

You should be able to use dbutils.notebooks.run for calling another notebook, but there is a difference between it and %run:

  • dbutils.notebooks.run executes another notebook as a separate job, so no definitions, etc. is pulled into the context of the current notebook - you can communicated data via temp views, etc.
  • %run execute another notebook and pulls all definitions and sides effects into the context of the current notebook.

I'm not sure if dbutils.notebooks.run will help in your case.

P.S. I personally would recommend to use %run with notebooks that only define functions, not doing any calculations, etc. - in this case, even if you have %run this doesn't cause any side effect on your current context.
