New features

  • The adjust = "t" option now supports Mielke’s strong k-out-of-m adjustment.
  • Diagnostic and sample-size plots now support endpoint selection.
  • Count-outcome workflows now support Poisson and negative-binomial sensitivity analyses, with expanded documentation.

Minor improvements and fixes

  • update() now handles comparator, endpoint, mean, standard-deviation, and covariance information more consistently.
  • Negative-binomial dispersion scaling for aggregate counts in parallel designs is now correct.
  • Monte Carlo stability and precision diagnostics are improved.

Bug fixes

  • A negative value (-1) is now handled correctly in relevant C++ code, avoiding an unsigned int conversion error.
  • Fixed CRAN review issues: expanded description, added references, documented function outputs.
  • Initial CRAN submission.
