Plot Boxes

Provides a boxplot for each group or variable.

Usage

# S3 method for data.frame
plotBoxes(frame, add=FALSE, main=NULL, ylab="Outcome", xlab="", ylim=NULL, offset=0, scale=.8, border="black", col=rgb(0, 0, 0, 0), values=TRUE)

# S3 method for formula
plotBoxes(formula, add=FALSE, main=NULL, ylab="Outcome", xlab="", ylim=NULL, offset=0, scale=.8, border="black", col=rgb(0, 0, 0, 0), values=TRUE)

Arguments

frame

a set of (non-empty) numeric vectors of data values

formula

a formula of the form lhs ~ rhs where lhs is a numeric variable giving the data values and rhs a factor giving the corresponding groups

add

whether the plot should added to the existing plot

ylab

a label for the y-axis

xlab

a label for the x-axis

main

a custom title for the graph

ylim

custom limits for the y axis

offset

a value indicating the offset of the boxplot

scale

a value that indicates the width of the boxplot

col

a value for the shaded color of the boxplot

border

a value for the border color of the boxplot

values

whether the values should be added to the boxplot

digits

the specified number of decimal places

Details

`plotBoxes` can be used to initialize a new plot or add to an existing plot (using the `add` argument). `addBoxes` is identical to `plotBoxes` without the need to utilize the `add` argument.

Value

The returned plot contains the following components:

LW

the lower whisker

LH

the lower hinge

Mdn

the median value

UH

the upper hinge

UW

the upper whisker
