In this workshop you will be working with the officer and flextable packages to create sophisticated clinical reports in Word format using R with a reproducible approach. Going from clinical data all the way through to complete pharmaceutical report generation. Specifically, we will walk through an end-to-end example focusing on advanced document structure management, complex table creation following pharmaceutical standards, and integration of ggplot2 visualizations. The workshop is divided into two parts: first, discovering the fundamentals of officer and flextable packages, then moving to advanced clinical reporting techniques including section management, headers and footers customization, and cross-reference handling for complete pharmaceutical report composition.
