barplot.acomp {compositions} | R Documentation

## Bar charts of amounts

### Description

Compositions and amounts dispalyed as bar plots.

### Usage

    ## S3 method for class 'acomp':
    barplot(height,...,legend.text=TRUE,beside=FALSE,total=1)
    ## S3 method for class 'rcomp':
    barplot(height,...,legend.text=TRUE,beside=FALSE,total=1)
    ## S3 method for class 'aplus':
    barplot(height,...,legend.text=TRUE,beside=TRUE)
    ## S3 method for class 'rplus':
    barplot(height,...,legend.text=TRUE,beside=TRUE)

### Arguments

`height` | an acomp, rcomp, aplus, or rplus object giving amounts to be displayed
`...` | further graphical parameters as in `barplot`
`legend.text` | same as legend.text in `barplot`
`beside` | same as beside in `barplot`
`total` | The total to be used in displaying the composition, typically 1, 100 or the number of parts

### Details

The functions are essentially light-weighted wrappers for `barplot`, just adding an adequate default behavior for each of the scales.

### Value

A numeric vector (or matrix, when `beside = TRUE`) giving the coordinates of all the bar midpoints drawn, as in `barchart`

    barplot(mean(acomp(sa.lognormals[1:10,])))
    barplot(mean(rcomp(sa.lognormals[1:10,])))
    barplot(mean(aplus(sa.lognormals[1:10,])))
    barplot(mean(rplus(sa.lognormals[1:10,])))

    barplot(acomp(sa.lognormals[1:10,]))
    barplot(rcomp(sa.lognormals[1:10,]))
    barplot(aplus(sa.lognormals[1:10,]))
    barplot(rplus(sa.lognormals[1:10,]))
