plot.LexCHCca: Plots for Chronological Constrained Hierarchical Clustering from LexCHCca Objects

Description

Plots graphs from LexCHCca results: tree, barplot of the aggregation criterion values and first CA map with the documents colored in accordance with the cluster.

Usage

# S3 method for LexCHCca
plot(x, axes=c(1, 2), choice="tree", rect=TRUE, title=NULL, ind.names=TRUE,
    new.plot=FALSE, max.plot=15, tree.barplot=TRUE,...)

Arguments

x

object of LexCHCca class

axes

length-2 vector defining the axes of the CA map to plot (by default (1,2))

choice

type of graph. "tree" plots the tree; "bar" plots the barplot of the successive values of the aggregation criterion (downward reading of the tree); "map" plots the CA map where the individuals are colored in accordances with the cluster of belonging (by default "tree")

rect

if TRUE, when choice="tree" rectangles are drawn around the clusters (by default TRUE)

title

title of the graph. If NULL, a title is automatically defined (by default NULL)

ind.names

if TRUE, the document labels are written on the CA map (by default TRUE)

new.plot

if TRUE, a new window is opened (by default FALSE)

max.plot

maximum of bars in the bar plot of the aggregation criterion (by default 15)

tree.barplot

if TRUE, the barplot of intra inertia losses is added on the tree graph (by default TRUE)

…

further arguments passed from other methods...

Value

Returns the chosen plot
