The emphasis In such cases will probably be on clarity of consumer interface and documentation, which Recommended Reading means design and style and code overview are very important. Robustness and testing are crucial in such a project much too.
Although R is an open up-supply project supported because of the community creating it, some providers try to offer professional guidance and/or extensions for their clients. This section offers some examples of these firms.
