plot.post.hoc: A function for visual representation of pairwise testing...

In pbiecek/PBImisc: A Set of Datasets Used in My Classes or in the Book 'Modele Liniowe i Mieszane w R, Wraz z Przykladami w Analizie Danych'

Description

Plot sets of groups in which means of medians are not significantly different.

On the veritical axis the means are marked. Then in a greedy fashion means that are not significantly different are linked by a line.

Usage

 plotPairwiseTests(p.vals, means, alpha=0.05, digits=3, mar=c(2,10,3,1), ...) 
 

Arguments

p.vals	A slot $p.value from the object returned by pairwise.*.test function
means	A vector of means or medians corresponding to p.vals object (the order of groups should be the same in both objects)
alpha	A threshold for p.value
digits	Number of significant digits to be ploted with means.
mar	Figure margins, left margin should be large enought to handle names of groups
...	These arguments are passed to the plot function.

Examples

data(iris)
tmp1 <- pairwise.wilcox.test(iris$Sepal.Width, iris$Species)
tmp2 <- tapply(iris$Sepal.Width, iris$Species, median, na.rm=TRUE)
plotPairwiseTests(tmp1$p.value, tmp2, alpha=0.001)
