In qmrobust: Quality Management: Examples from the concrete industry

Description

Plots the data and statistics of an interlaboratory study

Usage

## S3 method for class 'interlab'
plot(x, data=NULL, sd = TRUE, difflimits = FALSE,
     ylim = NULL, grouplabels = NULL, cex.text = 1.1, col = "blue", ...)

Arguments

x	an object of S3-class interlab
data	Data set containing the variables that appear in x$call$formula. Not needed if object contains the data.
sd	logical: should the standard deviations (within and betweengroups) be plotted?
difflimits	logical: should the standard deviations (within and betweengroups) be plotted?
ylim	Limits for the y axis.
grouplabels	Labels for the groups. Defaults to codesubstring(lev,1,3), where lev are the levels of the group factor
cex.text	Size of the text labelling the standard deviations
col	Color to be used for the group means and the respective standard deviation
...	Further arguments passed to plot.default

Examples

data(d.perm)
dd <- d.perm[d.perm$section=="w.1",]
dd[dd$team=="E","perm.log"] <- dd[dd$team=="E","perm.log"] - 0.3
  ## otherwise, there is no between group variation
r.cl <- interlabstats(perm.log~team, data=dd)
plot(r.cl)
