I'm working on a machine with no connectivity to the internet and integrated R using this link:

For the CRAN mirror, I have given the location of the local directory where packages are placed:


However, it isn't able to pick up the packages from the local directory and is throwing this error:

The packages needed by R are placed in the directory: /opt/dss/R-packages/R-packages/


Could you please advise on how to move forward with this?



I have successfully worked with miniCRAN, a packaged created and used by Microsoft's Revolution Analytics to mirror packages necessary to install R in a disconnected environment.

First, install miniCRAN in your Internet-connected environment and follow the vignettes on how to mirror the set of packages. miniCRAN will then layout the packages in a CRAN-compatible format. Once complete, move the folder from this environment into your disconnected Dataiku environment. After the folder is moved, you will need to point Dataiku at the location of this new folder for the redirection of all CRAN calls. This is located in the Administration --> Settings --> Misc section. There you will find the CRAN mirror URL. You will then place the local mapped folder location in the CRAN mirror URL location. Dataiku expects the following format for local folders:
file://<parent folder>/<sub folder>/miniCRAN

Note: the Dataiku user on the server must have access to this folder in order for it to work correctly. Hopefully this helps.

At the moment, the download-R-packages script can only be used for the base installation of DSS, not for code envs.

For code envs, you'll need to create a real CRAN mirror. There are various R packages that can help you for that.
