survSampleSize 0.1.2

• Fixed a platform-specific rounding difference in the ‘lrstat’ sample size test that caused a failure on macOS (ARM64). The test now accepts the correct result on both Windows and macOS.

survSampleSize 0.1.1

• Addressed CRAN review comments:
  • Software and package names (‘shiny’, ‘lrstat’, ‘powerSurvEpi’) are now written in single quotes in the Description.
  • Added ‘testthat’ unit tests for the internal (non-exported) calculation functions, so that breaking changes in R or in the upstream packages are detected automatically.
• Moved ‘lrstat’ and ‘powerSurvEpi’ from Suggests to Imports, as they are now used directly by the package’s internal calculation engine.

survSampleSize 0.1.0

• Initial release.
• run_app() launches an interactive Shiny application for survival-endpoint sample size and power calculation.
• Implements the Lu (2021) weighted log-rank method (via lrstat) and the Freedman (1982) method (via powerSurvEpi), with survival-curve and event-prediction visualisations and a method comparison.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
