phyloseq

phyloseq provides an R-based framework for import, storage, analysis, and visualization of microbiome census data generated by DNA sequencing.

Key Features:

• Object-Oriented Representation: Uses an object-oriented data structure to represent and manage microbiome data within R.
• Data Import and Compatibility: Supports importing data from various common file formats for microbiome census datasets.
• Comprehensive Analysis Techniques: Implements calibration, filtering, subsetting, agglomeration, multi-table comparisons, diversity analysis, parallelized Fast UniFrac, and ordination methods.
• Integration with R Packages: Interoperates with other R packages to apply additional analytical functions to its data structures.
• Visualization: Generates graphics for representation and interpretation of microbiome analyses.

Scientific Applications:

• Ecology: Enables analysis of ecological patterns in microbial communities.
• Genetics: Supports integration of genetic information in microbiome studies.
• Phylogenetics: Facilitates phylogenetic analyses, including Fast UniFrac comparisons.
• Multivariate Statistics: Supports multivariate statistical analyses and ordination methods for community data.
• Visualization and Testing: Provides visualization and statistical testing workflows for microbiome datasets.

Methodology:

Implements an object-oriented R data structure to import microbiome census data from common formats and perform calibration, filtering, subsetting, agglomeration, multi-table comparisons, diversity analysis, parallelized Fast UniFrac, ordination, and visualization while interoperating with other R packages.
