Structure and formatting requirements for clinical trial table and listing outputs vary between pharmaceutical companies. junco provides additional tooling for use alongside the rtables', rlistings and tern packages when creating table and listing outputs. While motivated by the specifics of Johnson and Johnson Clinical and Statistical Programming's table and listing shells, junco provides functionality that is general and reusable. Major features include a) alternative and extended statistical analyses beyond what tern supports for use in standard safety and efficacy tables, b) a robust production-grade Rich Text Format (RTF) exporter for both tables and listings, c) structural support for spanning column headers and risk difference columns in tables, and d) robust font-aware automatic column width algorithms for both listings and tables.
