Provides a plot of all group or level means and their confidence intervals.

Usage

# S3 method for data.frame
plotMeans(frame, ylab="Outcome", xlab="", mu=0, conf.level=.95, rope=NULL, values=TRUE, main=NULL, ylim=NULL, digits=3)

# S3 method for formula
plotMeans(formula, ylab="Outcome", xlab="", mu=0, conf.level=.95, rope=NULL, values=TRUE, main=NULL, ylim=NULL, digits=3)

# S3 method for wsm
plotMeans(moments, ylab="Outcome", xlab="", mu=0, conf.level=.95, rope=NULL, values=TRUE, main=NULL, ylim=NULL, digits=3)

# S3 method for bsm
plotMeans(moments, ylab="Outcome", xlab="", mu=0, conf.level=.95, rope=NULL, values=TRUE, main=NULL, ylim=NULL, digits=3)

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

moments

a matrix/frame of descriptive/summary statistics

ylab

a label for the y-axis

xlab

a label for the x-axis

mu

a number indicating the true/hypothesized value of the mean

conf.level

confidence level of the interval

line

a number for a horizontal reference line

rope

lower and upper values for a region of practical equivalence

values

whether the points should be labeled with their values

main

a custom title for the graph

ylim

custom limits for the y axis

digits

the specified number of decimal places

Details

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

Value

The returned plot contains the following components:

M

the means for the variables or groups

LL

the lower limits of the confidence intervals of the means

UL

the upper limits of the confidence intervals of the means

mu

a horizontal line for the true/hypothesized value

rope

a shaded region of practical equivalence
