group.abund.Taxa: Barplot Of Distribution Of Taxa In Groups

In RAM: R for Amplicon-Sequencing-Based Microbial-Ecology

Description

This function do a barplot to show the distribution of selected taxa in each level of a given metadata variable

Usage

group.abund.Taxa(data, is.OTU=TRUE, rank="g", taxa,
                 drop.unclassified=FALSE, bar.width=NULL,
                 meta, meta.factor="", RAM.theme=NULL,
                 col.pal=NULL, main="",
                 file=NULL, ext=NULL, height=8, width=16)

Arguments

data	a list of otu tables or taxonomic abundance matrices. See also RAM.input.formatting.
is.OTU	logical. If an OTU table was provided, is.OTU should be set as TRUE; otherwise, it should be set as FALSE.
rank	a single taxonomic rank. See also RAM.rank.formatting
taxa	a vector containing taxa names for plotting.
drop.unclassified	logical. Whether or not drop the unclassified taxon groups.
bar.width	width of bars
meta	the metadata table to be used (must have same samples as data.
meta.factor	a character string. Must be one of the metadata variables.
RAM.theme	customized ggplot_theme in RAM. See also ?theme_ggplot.
col.pal	color palettes to be used.
main	a character string. The title of the plot, default is an empty string.
file	filename to save the plot.
ext	filename extension, the type of image to be saved to.
width	an integer, width of the plot.
height	an integer, height of the plot.

Value

This function returns a Barplot of the distribution of seleted taxa within each level of a given metadata variable.

Note

This funtion provide an alternative view of taxa distribution as group.Taxa.bar.

Examples

data(ITS1, ITS2, meta)
taxa <- c("Fusarium", "Alternaria", "Cladosporium")
#otu tables
data <- list(ITS1=ITS1, ITS2=ITS2)
group.abund.Taxa(data=data, taxa=taxa, meta=meta,
                 meta.factor="Crop", drop.unclassified=TRUE)
#abundance tables
ITS1ab <- tax.abund(ITS1, rank="g")
ITS2ab <- tax.abund(ITS2, rank="g")
group.abund.Taxa(data=list(ITS1ab=ITS1ab, ITS2ab=ITS2ab), 
                 is.OTU=FALSE, taxa=taxa,
                 meta=meta, meta.factor="Crop", 
                 drop.unclassified=TRUE)
