normalPlot: Half-Normal plot

Description

function to generate a half-normal plot of the factor effects for an object of class facDesign.

Usage

normalPlot(fdo, threeWay = FALSE, na.last = NA, alpha = 0.05, sig.col = c("red1", "red2", "red3"), main, ylim, xlim, xlab, ylab, pch, col, border = "red", ...)

Arguments

fdo

object of class facDesign.

threeWay

TRUE/FALSE plot three-way or higher interactions. By default threeWay is set to FALSE.

na.last

By default set to NA.

alpha

alpha for marking interactions.

sig.col

vector - colors for marking significant interactions. By default sig.col is set to c("red1", "red2", "red3").

main

graphical parameter. A main title for the plot, see also title.

ylim

graphical parameter. The y limits of the plot.

xlim

graphical parameter. The x limits (x1, x2) of the plot. Note that x1 > x2 is allowed and leads to a reversed axis.

xlab

graphical parameter. A label for the x axis, defaults to a description of x.

ylab

graphical parameter. A label for the y axis, defaults to a description of y.

pch

graphical parameter. Vector containing numerical values or single characters giving plotting points for the different factors. See points for possible values and their interpretation. Note that only integers

col

graphical parameter. Single numerical value or character string giving the color for the points.

border

graphical parameter. Single numerical value or character string giving the color of the border line.

...

further graphical parameters see par.

Examples

fdo = facDesign(k=3, replicates = 2)  #factorial design
set.seed(123) #seed for random numbers
y = rnorm(nrow(fdo))  #random numbers
response(fdo) = y #set the response
normalPlot(fdo) #create a normal plot
