create-r-dockerfile

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The Dockerfile runs R commands at build time that fetch and install R packages from CRAN (repos='https://cloud.r-project.org/'), and renv::restore() will similarly pull and install remote package code during the image build, so this external URL is used at runtime to fetch and execute required code (https://cloud.r-project.org/).
