R Documentation

Profile Plot of the Observations in Each Cluster

Description

Profile Plot of the Observations in Each Cluster

Usage

pplot_tree(data = NULL, tree = NULL, ncl = 2, title = NULL, x = NULL,
  xaxp = NULL, xlim = NULL, ylim = NULL, xlab = NULL, ylab = NULL,
  lwd = 2, pch = c(1:9, 0, letters[1:26], LETTERS[1:26]), lty = 1:5,
  col = 1:8, legend = "bottomleft")

Arguments

data	Data frame
tree	An class hclust object
ncl	A vector of the number of clusters
title	A title string to be printed at the top of the plot.
x	A vector of size ncol(data) specifying the horizontal location.
xaxp	x tick mark locations of the form c( from, to, # of intervals)
xlim	Horizontal axis spec: of the form c( min, max ) : Default is c(1,ncl)
ylim	Vertical axis spec: of the form c( min, max )
xlab	Horizontal axis label
lwd	Vector of the width of the lines
pch	Vector of the symbols in the lines
lty	Vector of the types of the lines
col	Vector of the colors of the lines
legend	The location of the legend or NULL.
ykab	Vertical axis label

Details

This function creats, for each of ncl clusters, profile plot of the observations in each of cluster.

When legend overlapps the plot, try legend="topleft". Or, use legend="" and add legend manually by controlling ylim parameter.

Examples

Y <- demodata[,1:8]
set.seed(1701)
resY2 <- hclust( dist(Y) )
pplot_tree( Y, resY2, 3, title="Main Result", ylim=c(-2,10) )
resY3 <- dhclust( Y, maxclustersize=3 )
pplot_tree( Y, resY3$tree_l, 3, title="from Large", ylim=c(-2,10) )
pplot_tree( Y, resY3$tree_s, 3, title="from Short", ylim=c(-2,10) )
