plot.LexCHCca function

Plots for Chronological Constrained Hierarchical Clustering from LexCHCca Objects

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. UTF-8

## 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...

Returns

Returns the chosen plot
