The WR package implements various win ratio methodologies for composite endpoints of death and non-fatal events, including the (stratified) proportional win-fractions (PW) regression models (Mao and Wang, 2020 doi:10.1111/biom.13382), (stratified) two-sample tests with possibly recurrent nonfatal event, and sample size calculation for standard win ratio test (Mao et al., 2021 doi:10.1111/biom.13501).

Install WR from CRAN with:

install.packages("WR")

You can install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("lmaowisc/WR")

Here is a basic example.
