fur documentation

fur

fur is an example of how HARP can be run in a Docker container. HARP is a verification toolbox mainly for numerical weather prediction, written in R. For HARP references see the HARP GitHub repo.

fur has been developed by the NWP group at the Danish Meteorological Institute (DMI).

what problem does it solve?

HARP is written in R and have multiple R-package dependencies. Dealing with R packages can be a nightmare across platforms. Breaking changes is not a rare phenomenon and so compiling and installing HARP and share code across collaborations is not failsafe.

fur is a Docker image which contains a frozen installation of HARP and R. This makes the environment independent from the official HARP repository which gets commits directly onto the master-branch. From the fur image one can develop and run code that has HARP as a dependency and share that with other users of fur without having to deal with R environments.
