microbiomeMarker is still under development, your suggestion and contribution will be highly appreciated. If you think this project is helpful to you, you can give this project a ⭐.

The aim of this package is to build a unified toolbox in R for microbiome biomarker discovery by integrating existing widely used differential analysis methods.

Install the package from Bioconductor directly:

if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")

BiocManager::install("microbiomeMarker")

Or install the development version of the package from Github.

if (!requireNamespace("remotes", quietly=TRUE))
  install.packages("remotes")
remotes::install_github("yiluheihei/microbiomeMarker")

For more details on how to use microbiomeMarker, please see the help page or website of our package.
