Plot.hierarchy(object, dend, col=1:2, lwd=1:2, collab, returndend=FALSE, cex.labels=1.5, ...)

Arguments

object

object of class GAhier

onlySingleton

if TRUE, only names of singleton variables within the significant nodes are returned

dend

dendrogram object specifying the hierarchy of the variables

col

colors for significant and non-significant nodes and branches, respectively

lwd

line width for branches to non-significant and significant nodes, respectively

collab

vector of colors for coloring dendrogram leave labels (can be independent of significant/non-significant nodes); has to be named according to variable names; if missing, significant and non-significant variables are colored using colors defined in col

returndend

if TRUE, updated dendrogram object is returned (e.g. for use in further plots)

cex.labels

size of leave labels

...

further graphical parameters, passed to plot.dendrogram

Slots

clustervariables:

Object of class "list" containing names of variables in each tested cluster

p.values:

Object of class "list" containing p-values for each tested cluster

alpha:

Object of class "numeric"; chosen global significance level; if K had been specified, this additionally contains the adjusted significance levels for the K sub-hierarchies

n.variables:

Object of class "numeric"; number of variables in total

permstats:

Object of class "matrixOrNULL"; if returnPermstats had been set to TRUE, this is a matrix containing individual statistics for all variables for all permutations, otherwise NULL

Methods

show

signature(object = "GAhier"): Show general information and significant end nodes

results

signature(object = "GAhier"): Get a data.frame with significant end nodes, number and names of variables included in each node and corresponding p-value

sigEndnodes

signature(object = "GAhier"): Get names of signficant end nodes

Plot.hierarchy

signature(object = "GAhier"): Plot hierarchy dendrogram, where significant nodes (and branches to those nodes) are highlighted

Note

Coloring the dendrogram in Plot.hierarchy is based on functionality from the globaltest package
