In swCRTdesign: Stepped Wedge Cluster Randomized Trial (SW CRT) Design

swCRTdesign

swCRTdesign includes functions for the design and analysis of stepped wedge cluster randomized trials.

Installation

You can install the development version of swCRTdesign like so:

# install.packages("devtools")
devtools::install_github("jphughes9/swCRTdesign")

Example

This is a basic example which shows you how find the power of a SW trial with 24 clusters and 5 periods

library(swCRTdesign)
swPwr(swDsn(c(6,6,6,6)), distn="binomial",
n=120, mu0=0.05, mu1=0.035, tau=0.01, eta=0, rho=0, gamma=0, alpha=0.05, retDATA=FALSE)
#> Warning in swPwr(swDsn(c(6, 6, 6, 6)), distn = "binomial", n = 120, mu0 = 0.05,
#> : Cross-sectional design assumed
#> treatment.1 
#>   0.7861896

#You’ll still need to render README.Rmd regularly, to keep README.md up-to-date. #devtools::build_readme() is handy for this.

#In that case, don’t forget to commit and push the resulting figure files, so they #display on GitHub and CRAN.
