The goal of daa is to provide method for differential abundance analysis (DAA).

Get the latest stable R release from CRAN. Then install daa from Bioconductor using the following code:

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

BiocManager::install("daa")

And the development version from GitHub with:

BiocManager::install("microbiome/daa")

This is a basic example which shows you how to solve a common problem:

library("daa")
## basic example code

What is special about using README.Rmd instead of just README.md? You can include R chunks like so:

summary(cars)
#>      speed           dist       
#>  Min.   : 4.0   Min.   :  2.00  
#>  1st Qu.:12.0   1st Qu.: 26.00  
#>  Median :15.0   Median : 36.00  
#>  Mean   :15.4   Mean   : 42.98  
#>  3rd Qu.:19.0   3rd Qu.: 56.00  
#>  Max.   :25.0   Max.   :120.00

You’ll still need to render README.Rmd regularly, to keep README.md up-to-date.

You can also embed plots, for example:

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

Below is the citation output from using citation('daa') in R. Please run this yourself to check for any updates on how to cite daa.

print(citation("daa"), bibtex = TRUE)
#> To cite package 'daa' in publications use:
