Plot Frequencies

Provides a frequency distribution for each group or variable.

Usage

# Default S3 method
plotFrequencies(variable, add=FALSE, ylim=NULL, main=NULL, ylab=NULL, xlab="", type="right", offset=.1, col="black")

# S3 method for class 'data.frame'
plotFrequencies(frame, add=FALSE, ylim=NULL, main=NULL, ylab=NULL, xlab="", type="right", offset=.1, col="black")

# S3 method for class 'formula'
plotFrequencies(formula, add=FALSE, ylim=NULL, main=NULL, ylab=NULL, xlab="", type="right", offset=.1, col="black")

Arguments

variable

a numeric vector of data values

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

type

side on which the distribution should be displayed

offset

a value indicating the offset of the plot

col

a value for the shaded color of the plot

Details

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

Value

The returned plot contains frequency distributions for the groups or variables.
