ANOM (version 0.5)

ANOMgen:

Description

Graphical representation of the analysis of means: convert simultaneous confidence intervals (that were computed with ANY method) into ANOM decision limits and draw a decision chart as commonly used in technometrics.

Usage

ANOMgen(mu, n=NULL, gm=NULL, lo, up, names, alternative="two.sided",
        xlabel="Group", ylabel="Endpoint", printn=TRUE, p=NULL, bg="white",
        bgrid=TRUE, axlsize=18, axtsize=25, npsize=5, psize=5, lwidth=1,
        dlstyle="dashed", fillcol="darkgray")

Arguments

mu
A numeric vector of group means.
n
A numeric vector of sample sizes per group. Either n or gm must be provided.
gm
A single numeric value giving the grand mean of all groups. Either n or gm must be provided.
lo
A numeric vector of lower (simultaneous) confidence interval bounds for comparisons to the grand mean.
up
A numeric vector of upper (simultaneous) confidence interval bounds for comparisons to the grand mean.
names
An (optional) vector of characters specifying the groups' names.
alternative
A character string indicating the direction of the alternative hypothesis. Default is "two.sided", but may be changed to one-sided alternatives (either "greater" or "less").
xlabel
A character string specifying the label of the horizontal axis.
ylabel
A character string specifying the label of the vertical axis.
printn
A logical. Should per-group sample sizes be included in the chart? Default is TRUE. If n ist left at NULL, the function automatically sets printn to FALSE.
p
An (optional) numeric vector of (simultaneous) p-values to be printed.
bg
A character string. Should the plot's background be "white" (default) or "gray" (or "grey")?
bgrid
A logical. Should background grid lines be plotted? Default is TRUE.
axlsize
A numerical value specifying the font size of the axis labels. Default is 18.
axtsize
A numerical value specifying the font size of the axis titles. Default is 25.
npsize
A numerical value specifying the font size of the sample sizes and p-values (if printed). Default is 5.
psize
A numerical value specifying the size of the points (group means). Default is 5.
lwidth
A numerical value specifying the width of the lines (grand mean, decision limits, vertical connections). Default is 1.
dlstyle
A character string specifying the style of the decision limits. Default is "dashed".
fillcol
A character string specifying the color of the area of no significant deviation from the grand mean. Default is "darkgray".

Value

An ANOM decision chart.

Details

This is a generic tool that translates (simultaneous) confidence intervals into ANOM decision limits.
