In hettx: Fisherian and Neymanian Methods for Detecting and Measuring Treatment Effect Variation

hettx 1.0.1

• Fixed CRAN submission NOTEs (excluded cran-comments.md and CRAN-SUBMISSION from package build).

hettx 1.0.0

New features

• Added tidy() and glance() methods for all result objects (FRTCI.test, RI.regression.result, RI.R2.result) via the generics package, enabling tidyverse-style workflows.

• Added test_stat_info() with structured output and dynamic formatting, replacing the old hard-coded text display.

Function renaming

• All user-facing functions have been renamed from dot-case to snake_case for consistency with modern R conventions:

  • detect_idiosyncratic() and estimate_systematic() (unchanged)
  • get.p.value() -> get_p_value()
  • variance.ratio.test() -> variance_ratio_test()
  • make.randomized.dat() -> make_randomized_dat()
  • make.randomized.compliance.dat() -> make_randomized_compliance_dat()
  • test.stat.info() -> test_stat_info()
  • All test statistic functions: KS.stat -> KS_stat, SKS.stat -> SKS_stat, SKS.stat.cov -> SKS_stat_cov, etc.
  • make.linear.data() -> make_linear_data(), make.quadradic.data() -> make_quadradic_data(), make.skew.data() -> make_skew_data()

• The old dot-case names continue to work but emit deprecation warnings via .Deprecated(). They will be removed in a future release.

Dependency changes

• Removed formula.tools dependency; replaced with base R formula parsing (all.vars(), manual LHS/RHS extraction).

• Removed plyr dependency; replaced plyr::ddply()/plyr::summarize() with base R aggregate() in test statistic functions.

• Removed unused dplyr, tidyr, and purrr imports.

• Added generics to Imports (for tidy() and glance() methods).

Code quality improvements

• Standardized assignment operators to <- throughout the codebase.

• Replaced class(x) %in% with inherits() for proper S3 class checking.

• Replaced sapply() with vapply() (explicit FUN.VALUE) across the codebase for type-safe apply operations.

• Renamed internal dot-case helper functions to snake_case.

• Added roxygen documentation to internal helper functions in helper_frt.R.

Infrastructure

• Bumped minimum R version from 2.14.0 to 4.0.0.

• Removed unnecessary stringsAsFactors = FALSE arguments (default since R 4.0.0).

• Removed redundant manual @usage roxygen tags (17 instances).

• Updated expect_is() to expect_s3_class() in tests.

• Fixed CRAN NOTE: arXiv references now use DOI format (doi:10.48550/arXiv.XXXX.XXXXX).

• Added importFrom(stats, terms) to NAMESPACE.

• Added R-hub GitHub Actions workflow for cross-platform CRAN check testing.

• Added cross-branch equivalence tests verifying numeric results match the previous release.
