Object Design for Package Cohorts

Cohort Object Qualities

• Immutable - Changes to component packages would result in a new cohort.
• Contingent on dependancies - All packages, both explicit and implicit dependancies effect cohort risk.
• Constructable from a list of packages, repository, or library.

Issues Referencing Cohorts

• Strategy for cohort metrics
• Define a class for a cohort of R packages and its metrics
• Define methods for cohort metric class
• Cohort Metric for Namespace Conflicts
