Overview
BRCore provides a unified framework for identification and ecological interpretation of core microbiomes across time and space, enhancing robustness and reproducibility in microbiome data analysis.
BRCore provides tools for:
Rarefaction analysis: Calculate pre-rarefaction metrics and perform rarefactions
add_rarefaction_metrics()
multi_rarefy()
plot_variance_propagation()
Core microbiome identification: Identify core microbial taxa using abundance-occupancy distributions
identify_core()
Neutral model fitting: Fit and visualize neutral community models
fit_neutral_model()
plot_neutral_model()
sncm.fit()
Visualization: Plot rarefaction diagnostics, abundance-occupancy curves, and core distributions
plot_rarefaction_metrics()
plot_abundance_occupancy()
plot_core_distribution()
plot_identified_core()
