Description

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

Usage

group.Taxa.box(data, is.OTU=TRUE, rank="g", 
               taxa="", meta, meta.factor="",      
               cex.y=5, cex.x=5, 
               RAM.theme=NULL, col.pal=NULL, main="", 
               file=NULL, ext=NULL, height=8, width=16)

Arguments

data

Value

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

Examples

data(ITS1, ITS2, meta)
taxa <- c("Fusarium", "Alternaria", "Cladosporium")
group.Taxa.box(data=list(ITS1=ITS1, ITS2=ITS2), is.OTU=TRUE, rank="g", 
           taxa=taxa, meta=meta, meta.factor="City")
taxa.1 <- c("Fusarium", "Alternaria", "Cladosporium", "Verticillium",
           "Kondoa")
group.Taxa.box(data=list(ITS1=ITS1, ITS2=ITS2), is.OTU=TRUE, rank="g", 
           taxa=taxa.1, meta=meta, meta.factor="City")
