%description
Build robust and maintainable software with object-oriented design
patterns in R. Design patterns abstract and present in neat, well-defined
components and interfaces the experience of many software designers and
architects over many years of solving similar problems. These are
solutions that have withstood the test of time with respect to
re-usability, flexibility, and maintainability. 'R6P' provides abstract
base classes with examples for a few known design patterns. The patterns
were selected by their applicability to analytic projects in R. Using
these patterns in R projects have proven effective in dealing with the
complexity that data-driven applications possess.
