Plot Means Pairwise

Provides a plot of all unadjusted pairwise comparisons and their confidence intervals.

Usage

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

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

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

# S3 method for bsm
plotMeansPairwise(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

Value

The returned plot contains the following components:

Diff

the differences between the pairs of means

LL

the lower limits of the confidence intervals for the differences

UL

the upper limits of the confidence intervals for the differences

mu

a horizontal line for the true/hypothesized value

rope

a shaded region of practical equivalence
