In microbiome: Microbiome Analytics

Description Usage Arguments Details Value Author(s) References Examples

Show all samples of a microbiota collection, colored by specific factor levels (x axis) and signal (y axis).

1	plot_atlas(pseq, x, y, ncol = 2)

`pseq`	phyloseq object
`x`	Sorting variable for X axis and sample coloring
`y`	Signal variable for Y axis
`ncol`	Number of legend columns.

Arranges the samples based on the given grouping factor (x), and plots the signal (y) on the Y axis. The samples are randomly ordered within each factor level. The factor levels are ordered by standard deviation of the signal (y axis).
