boxplot {compositions} | R Documentation

## Displaying compositions and amounts with box-plots

### Description

For the different interpretations of amounts or compositional data, a different type of boxplot is feasible. Thus different boxplots are drawn.

### Usage

    ## S3 method for class 'acomp':
    boxplot(x,fak=NULL,...,
                             xlim=x.lim,ylim=c(minq,maxq),log=TRUE,
                             panel=vp.logboxplot,dots=!boxes,boxes=TRUE)
    ## S3 method for class 'rcomp':
    boxplot(x,fak=NULL,...,
                             xlim=x.lim,ylim=c(0,1),log=FALSE,
                             panel=vp.boxplot,dots=!boxes,boxes=TRUE)
    ## S3 method for class 'aplus':
    boxplot(x,fak=NULL,...,log=TRUE)
    ## S3 method for class 'rplus':
    boxplot(x,fak=NULL,...,ylim=c(0,max(x)),log=FALSE)
    vp.boxplot(x,y,...,dots=FALSE,boxes=TRUE,xlim,ylim,log,notch=FALSE)
    vp.logboxplot(x,y,...,dots=FALSE,boxes=TRUE,xlim,ylim,log,notch=FALSE)

### Arguments

`x` | a data set
`fak` | a factor to split the data set, not yet implemented in aplus and rplus
`xlim` | x-limits of the plot
`ylim` | y-limits of the plot
`log` | logical indicating whether ploting should be done on log scale
`panel` | the panel function to be used or a list of multiple panel functions
`...` | further graphical parameters
`dots` | a logical indicating whether the points should be drawn
`boxes` | a logical indicating whether the boxes should be drawn
`y` | used by pairs
`notch` | logical, should the boxes be notched?

### Details

`boxplot.aplus` and `boxplot.rplus` are wrappers of `bxp`, which just take into account the possible logarithmic scale of the data.

`boxplot.acomp` and `boxplot.rcomp` generate a matrix of box-plots, where each cell represents the difference between the row and column variables. Such difference is respectively computed as a log-ratio and a rest.

`vp.boxplot` and `vp.logboxplot` are only used as panel functions. They should not be directly called.
