All functions

align_bowtie2()

Aligns metagenomic shotgun sample against a reference

as.matrix(<mbquant>)

Convert a mbquant data table to a matrix.

association()

Run differential association tests between taxa counts and exogenous factors.

combinatorial_association()

download_index()

Builds index files for human sequence identification

find_taxa()

Checks whether taxa from one taxonomy table are contained in another table.

mbtools

mbtools.

mock_plot()

Creates a plot of measured taxa quantifications vs. reference quantification.

mockrobiota()

Downloads a complete data set from mockrobiota.

mothur_to_dada()

Converts taxa annotations from mothur format to dada2 format.

normalize()

Normalize a set of read counts across samples

orlitsky()

Orlitsky's diminishing attenuation estimator (q2/3).

plot_counts()

Plots counts for several taxa across a co-variable

plot_taxa()

Plots relative distribution for taxa across samples.

read_slimm()

Reads SLIMM output to a data table.

remove_organism()

Removes sequence contamination from another target organism (for instance human sequences).

run_slimm()

Quantifies abundances for the bacteria using SLIMM

split_barcodes()

Splits FASTQ files into individual samples.

sra_files()

List samples and read files in a directory.

standardize()

Standardize all continuous columns of a data frame.

taxa_count()

Counts the reads for a specific taxonomy level.

taxa_metrics()

Calculates what percentage of taxa was found in a reference set.

taxa_quants()

Compares taxa quantification from a measurement to a reference ground truth.

types()

Applies the specified types to a data frame-like object.
