PropTestR 1.0.0

Comprehensive two-proportion inference in R

PropTestR provides a single, standardized interface for comparing two independent or paired proportions, with emphasis on clinical trials, epidemiology, veterinary epidemiology, and biomedical research.

Installation

PropTestR 1.0.0 is currently a source package. Install its CRAN dependencies first:

install.packages(c("DescTools", "DescrTab2"))

Then install the local source package:

install.packages("PropTestR_1.0.0.tar.gz", repos = NULL, type = "source")

Main function

library(PropTestR)

result <- compare_2prop(
  x1 = 82, n1 = 100,
  x2 = 75, n2 = 100,
  method = "all"
)

print(result)
tidy_prop_result(result)
plot_prop_result(result)

Farrington-Manning non-inferiority

farrington_manning(
  x1 = 82, n1 = 100,
  x2 = 85, n2 = 100,
  margin = -0.10,
  alternative = "greater"
)

Equivalence

equivalence_2prop(
  x1 = 80, n1 = 100,
  x2 = 78, n2 = 100,
  margin = 0.10,
  conf.level = 0.90
)

Paired proportions

paired_2prop(b = 15, c = 5, n = 100)
paired_2prop(b = 15, c = 5, n = 100, method = "mcnemar_exact")

Stratified proportions

stratified_2prop(
  x1 = c(20, 15, 30), n1 = c(100, 80, 120),
  x2 = c(25, 18, 35), n2 = c(100, 80, 120),
  strata = c("A", "B", "C")
)

Version 1.0 methods

Independent groups: Wald, score, Pearson chi-squared, Yates-corrected chi-squared, Fisher exact, Barnard exact, Boschloo exact, Agresti-Caffo, Newcombe/score, Miettinen-Nurminen, Mee, Brown-Li-Jeffreys, and Farrington-Manning.

Additional procedures: risk difference, risk ratio, odds ratio, equivalence, McNemar paired analysis, and stratified Cochran-Mantel-Haenszel analysis.

Statistical validation

Version 1.0 should be validated against published reference examples and independent implementations before CRAN submission. The package deliberately uses established CRAN implementations for several computationally intensive procedures and standardizes their outputs rather than reimplementing copyrighted source code.

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.
