Downloading R libraries from CRAN to the laptop

Question

All,

Our Azure Databricks workspace does not have outbound access to the internet due to which we have to manually download libraries that are needed and upload them to the workspace.

I need to make nloptr library available in the cluster. Any idea how I can download this library to my laptop. I can only see Windows and MacOS binaries.

Thanks,
grajee

Hello @Gopinath Rajee ,
Thanks for the question and using MS Q&A platform.

As I understand, you disabled outbound traffic from your Databricks workspace, and now that makes installing libraries difficulty.
The ask, is what to download for nloptr.

To see what R would use, I spun up a cluster and tried to install.
install.packages("nloptr")

I found it downloads the source code rather than the binaries. Then it compiles and runs.

I noticed when trying to upload libraries, there was only jar and python options. So I'm not sure just uploading like that will work.
However, I think uploading as file into dbfs (as opposed to "new library") and then trying the install using the file rather than the remote package will work.

Please do let me if you have any queries.

Thanks
Martin

Answer 2

I was able to upload the tar.gz file into the cluster and add it as the library.
