Changes in version 1.0.0 Major changes - Initial release of the BreastSubtypeR package. - Implements NC-based and SSP-based molecular subtyping methods for breast cancer. - Provides an R Shiny app for users unfamiliar with R. Features - Comprehensive Intrinsic Subtyping for Breast Cancer: Integrates multiple published intrinsic subtyping methods, including NC-based approaches like the original PAM50 (Parker et al., J Clin Oncol, 2009) and SSP-based methods like AIMS (Paquet et al., J Natl Cancer Inst, 2015). - Multi-Method Subtyping Functionality: Simultaneously predicts breast cancer intrinsic subtypes using a variety of validated methods for comparative analysis. - AUTO Mode Feature: Evaluates the distribution of ER and HER2 status in the test cohort to automatically select subtyping methods that align with the cohort's characteristics, ensuring compatibility with method-specific assumptions for greater accuracy and reliability. - Optimized Gene Mapping: Optimizes gene mapping using Entrez IDs to maximize the inclusion of genes across subtyping methods. - Streamlined Input and Output: Provides standardized input/output formats to ensure smooth integration with other gene expression analysis tools. - User-Friendly Shiny App Interface: Features a web-based GUI that runs entirely locally, ensuring data privacy with no online sharing, ideal for users who prefer a visual interface over R scripting.
