Code Review

This pull request adds the dash system dependency to the Dockerfile. My review finds that this dependency is likely redundant, as dash is the default shell on the Debian-based r-base image and should already be present. I've recommended removing this unnecessary package installation to keep the Dockerfile clean.

[gemini-code-assist]

The r-base Docker image is based on Debian, where dash provides the default system shell at /bin/sh and is therefore already installed. Explicitly adding dash here is redundant. This line can be removed to keep the Dockerfile concise and avoid unnecessary dependency declarations.
