Run R script on ADF

Prakash14 126

i have a very small R script which needs to be run in ADF. What is the ideal solution for this ? Azure batch /Azure Function /Azure automation account /vm's(VM is existing and not new, how to connect vm's from ADF and execute R file). I got to know R language is not supported in Azure functions. Azure function alone is serverless ?Help me choose the right service for this.

Is it possible to use existing VM's instead of new Batch VM's ? Also how to run r scripts from Azure functions serverless ?

you cannot run R scripts in Azure functions as per my understanding.

I am not exactly sure whether the below approach would work but just a thought:

Set up Azure devops agent in that VM

create a release pipeline in Azure devops

Set up logic app to trigger Devops pipeline

Trigger logic app from ADF

The above flow is just a hypothetical flow and not sure that would work exactly .

1.Command - Rscript file.R

Error : Task failed "The specified command program is not found"

'Rscript' is not recognized as an internal or external command,
operable program or batch file.

Hello @Prakash14 ,

It will be hard without know which activity exactly throwing this error and all configuration details of that activity to repro and come to conclusion.

Still, by seeing error message it seems some where system is trying to look for a file but unfortunately its not able find it.

Could you please share details of activity throwing error along with configurations of that activity? Detailed steps you followed from starting to the error will help us better to repro scenario and debug for resolution.

I also had Error : Task failed "The specified command program is not found". As of July 2024 microsoft-dsvm --> dsvm-windows --> server-2016 shown on the above Github page is no longer available. The only offer for microsoft-dsvm is ubuntu-hpc of sku 2204, on which R is not installed. How to installed R on microsoft-dsvm --> ubuntu-hpc --> 2204? Or even better, is there a pool image that comes with R installed?
