Install R Packages in Azure ML

Question

Its my 1st time using Azure ML and I am having a rough time. I need to install multiple R packages that are not provided by default in Azure

Answer 1

Unfortunately yes. You can do 2 things.

1. First figure out which of the dependencies are already installed in azureml. See this blogpost

   Use Execute R script task in AML studio and copy paste the below script:

   out <- data.frame(installed.packages(,,,fields=”Description”))
   maml.mapOutputPort(“out”)
   

2. Collect all depended packages (imports and linkingto) and add these to the zip file (in the correct order) and follow the information in the blogpost you linked to.

I use option 1, since that limits the amount of packages needed. But be aware of version differences on azureML and cran.
