R support in Sonatype Nexus 3.7

What is R ? https://www.r-project.org/about.html but even better https://en.wikipedia.org/wiki/R_(programming_language)

What is CRAN ? https://cran.r-project.org/ and https://en.wikipedia.org/wiki/R_(programming_language)#CRAN

"A core set of packages is included with the installation of R, with more than 11,000 additional packages (as of July 2017) available at the Comprehensive R Archive Network (CRAN), Bioconductor, Omegahat, GitHub, and other repositories."

git clone https://github.com/sonatype-nexus-community/nexus-repository-r.git
cd nexus-repository-r/
git tag -l
git checkout tags/1.0.1
(you are now in detached head, who cares...)
or even better : git checkout tags/1.0.1 -b 1.0.1 (so you don't get a detached head)
WARNING: for Nexus version 3.8.0-02 and above use tag 1.0.1, otherwise 1.0.0
mvn clean install

customize the file as per https://github.com/sonatype-nexus-community/nexus-repository-r chapter "(most) Permanent Install" (careful! you must add 2 separate sections in the XML file! Nexus stinks, they should provide a CLI to manage plugins, instead of asking you to manually manipulate the XML )

docker stop 6f49bdc956a6
docker start 6f49bdc956a6

when you create a new repository, you should now see the r (group) r (hosted) and r (proxy) types
