Ploth: Changes the appearance of cluster dendrogram

In shipunov: Miscellaneous Functions from Alexey Shipunov

Changes the appearance of cluster dendrogram

Description

Modifies several aspects of the cluster dendrogram

Usage

  Ploth(hclust, labels=hclust[["labels"]], lab.font=1, lab.col=1, col=1,
   pch.cex=1, pch=NA, bg=0, col.edges=FALSE, hang=-1, ...)

Arguments

hclust	Hclust object
labels	Labels
lab.font	Label font
lab.col	Label colors
col	Colors of edges and points
pch.cex	Scale of points
pch	Point types
bg	Points backgrounds
col.edges	Colorize edges?
hang	Makes leaves hang, see plot.hclust(); -1 is default here whereas 0.1 is default for 'hclust'
...	Further arguments to plot.dendrogram()

Details

Changes the appearance of cluster dendrogram. If labels are long, you might need to modify the plot margins.

Please take into account that supplied labels are meant to be in their _initial_ order, not in order of their appearance on the dendrogram.

Ploth() does not change the text size of labels, please use Tctext() and Tcoords() for this (and other) purposes.

Examples

iris.dist <- dist(iris[, 1:4], method="manhattan")
iris.hclust <- hclust(iris.dist)
Ploth(iris.hclust, col=as.numeric(iris[, 5]), pch=16, col.edges=TRUE, horiz=TRUE,
 leaflab="none")
legend("topleft", fill=1:nlevels(iris[, 5]), legend=levels(iris[, 5]))

Ploth(hclust(UScitiesD, "ward.D2"), labels=abbreviate(attr(UScitiesD, "Labels")),
 lab.col=c(1, rep(2, 9)), lab.font=c(2, rep(1, 9)), hang=0.1)
