Introduction

PathoStat is a R shiny package, designed for performing Statistical Microbiome Analysis on metagenomics results from sequencing data samples. In particular, it supports analyses on the PathoScope generated report files.

The package includes:

• Data Summary and Filtering
• Relative Abundance plots (Stacked Bar Plot, Heatmap)
• Multiple species boxplot visualization
• Diversity analysis (Alpha and Beta diversity)
• Differential Expression (DEseq2, edgeR)
• Dimension Reduction (PCA, PCoA)
• Biomarker identification

Installation

To begin, install Bioconductor and simply run the following to automatically install PathoStat and all the dependencies as follows.

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

If you want to install the latest development version of PathoStat from Github, use devtools to install it as follows:

require(devtools)
install_github("mani2012/PathoStat", build_vignettes=TRUE)
