cluster (version 2.0.6)

bannerplot: Plot Banner (of Hierarchical Clustering)

Description

Draws a “banner”, i.e. basically a horizontal barplot visualizing the (agglomerative or divisive) hierarchical clustering or an other binary dendrogram structure.

Usage

bannerplot(x, w = rev(x$height), fromLeft = TRUE,
           main=NULL, sub=NULL, xlab = "Height",  adj = 0,
           col = c(2, 0), border = 0, axes = TRUE, frame.plot = axes,
           rev.xax = !fromLeft, xax.pretty = TRUE,
           labels = NULL, nmax.lab = 35, max.strlen = 5,
           yax.do = axes && length(x$order) 

Arguments

x

a list with components order, order.lab and height when w, the next argument is not specified.

w

non-negative numeric vector of bar widths.

fromLeft

logical, indicating if the banner is from the left or not.

main,sub

main and sub titles, see title.

xlab

x axis label (with ‘correct’ default e.g. for plot.agnes).

adj

passed to title(main,sub) for string adjustment.

col

vector of length 2, for two horizontal segments.

border

color for bar border; now defaults to background (no border).

axes

logical indicating if axes (and labels) should be drawn at all.

frame.plot

logical indicating the banner should be framed; mainly used when border = 0 (as per default).

rev.xax

logical indicating if the x axis should be reversed (as in plot.diana).

xax.pretty

logical or integer indicating if pretty() should be used for the x axis. xax.pretty = FALSE is mainly for back compatibility.

labels

labels to use on y-axis; the default is constructed from x.

nmax.lab

integer indicating the number of labels which is considered too large for single-name labelling the banner plot.

max.strlen

positive integer giving the length to which strings are truncated in banner plot labeling.

yax.do

logical indicating if a y axis and banner labels should be drawn.

yaxRight

logical indicating if the y axis is on the right or left.

y.mar

positive number specifying the margin width to use when banners are labeled (along a y-axis). The default adapts to the string width and optimally would also dependend on the font.

…

graphical parameters (see par) may also be supplied as arguments to this function.

Examples

# NOT RUN {
data(agriculture)
bannerplot(agnes(agriculture), main = "Bannerplot")
# }
