Colon Cancer Recurrence Data (Example Dataset)

Description

A processed subset of the colon dataset restricted to the recurrence endpoint (etype == 1), providing one row per patient. Variables have been relabelled with clinically descriptive names and factor levels suitable for direct use in TernTables functions. This dataset is provided as a ready-to-use example for demonstrating ternD() and ternG() functionality.
