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.
