plot.LexCHCca {Xplortext} | R Documentation |
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 class 'LexCHCca'
plot(x, axes=c(1, 2), type=c("tree","map","bar"), 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)) |
type |
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
