plot.HCPC | R Documentation |
Plots graphs from a HCPC result: tree, barplot of inertia gains and first factor map with or without the tree, in 2 or 3 dimensions.
## S3 method for class 'HCPC'
plot(x, axes=c(1,2), choice="3D.map", rect=TRUE,
draw.tree=TRUE, ind.names=TRUE, t.level="all", title=NULL,
new.plot=FALSE, max.plot=15, tree.barplot=TRUE,
centers.plot=FALSE, ...)
x |
A HCPC object, see |
axes |
a two integers vector.Defines the axes of the factor map to plot. |
choice |
A string. "tree" plots the tree. "bar" plots bars of inertia gains. "map" plots a factor map, individuals colored by cluster. "3D.map" plots the same factor map, individuals colored by cluster, the tree above. |
rect |
a boolean. If TRUE, rectangles are drawn around clusters if choice ="tree". |
tree.barplot |
a boolean. If TRUE, the barplot of intra inertia losses is added on the tree graph. |
draw.tree |
A boolean. If TRUE, the tree is projected on the factor map if choice ="map". |
ind.names |
A boolean. If TRUE, the individuals names are added on the factor map when choice="3D.map" or choice="map" |
t.level |
Either a positive integer or a string. A positive integer indicates the starting level to plot the tree on the map when draw.tree=TRUE. If "all", the whole tree is ploted. If "centers", it draws the tree starting t the centers of the clusters. |
title |
a string. Title of the graph. NULL by default and a title is automatically defined |
centers.plot |
a boolean. If TRUE, the centers of clusters are drawn on the 3D factor maps. |
new.plot |
a boolean. If TRUE, the plot is done in a new window. |
max.plot |
The max for the bar plot |
... |
Other arguments from other methods. |
Returns the chosen plot.

data(iris)
# Clustering, auto nb of clusters:
res.hcpc=HCPC(iris[1:4], nb.clust=3)
# 3D graph from a different point of view:
plot(res.hcpc, choice="3D.map", angle=60)
