plot.pairw: Plots confidence intervals for objects from class pairw

Description

Provides a utility confidence interval plotting function for objects of class = "pairw", i.e. objects from pairw.anova, pair.fried, and pairw.kw.

Usage

## S3 method for class 'pairw':
plot(x, col = 1, lty = NULL, lwd = NULL, cap.length = 0.1, xlab = "", main = NULL, ...)

Arguments

x

An object of class pairw.

col

Confidence bar color, see par.

lty

Confidence bar line type, see par.

lwd

Confidence bar line width, see par.

cap.length

Widths for caps on interval bars (in inches).

xlab

X-axis label.

main

Main cpation. Defaults to a descriptive head.

...

Additional arguments from barplot.
