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.
