upset_pq: Make upset plot for phyloseq object.

In MiscMetabar: Miscellaneous Functions for Metabarcoding Analysis

Make upset plot for phyloseq object.

Description

Alternative to venn plot.

Usage

upset_pq(
  physeq,
  fact,
  taxa_fill = NULL,
  min_nb_seq = 0,
  na_remove = TRUE,
  numeric_fonction = sum,
  rarefy_after_merging = FALSE,
  ...
)

Arguments

physeq	(required): a phyloseq-class object obtained using the phyloseq package.
fact	(required): Name of the factor to cluster samples by modalities. Need to be in physeq@sam_data.
taxa_fill	(default NULL) fill the ASV upset using a column in tax_table slot.
min_nb_seq	minimum number of sequences by OTUs by samples to take into count this OTUs in this sample. For example, if min_nb_seq=2,each value of 2 or less in the OTU table will not count in the venn diagram
na_remove	: if TRUE (the default), NA values in fact are removed if FALSE, NA values are set to "NA"
numeric_fonction	(default : sum) the function for numeric vector useful only for complex plot (see examples)
rarefy_after_merging	Rarefy each sample after merging by the modalities of fact parameter
...	Other arguments passed on to the ComplexUpset::upset()

Value

A ggplot2 plot
