Plot Means Posthoc — plotMeansPosthoc • EASI

Provides a plot of all Tukey HSD comparisons and their confidence intervals.

Usage

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

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

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

# S3 method for bss
plotMeansPosthoc(DescStats, 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
DescStats: 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
