R help - Nov 2009 - Labels in horizontal dendrogram not placed correctly?

Hi all,

I tried plotting a horizontal dendrogram, but it seems as if the
labels are not taken into account in the function plot.dendrogram().

A minimal example :
Test <- data.frame(
    x10000x = c(1:10),
    x20000x = c(2:11),
    x30000x = c(11:2)
)

TestDist <- daisy(data.frame(t(Test)))
TestAgnes <- agnes(TestDist)
plot(as.dendrogram(TestAgnes),horiz=T)

If I run this in R 2.10.0, I get a horizontal dendrogram with the
labels to the far right, and partly outside the plot area. This is
highly inconvenient. Am I doing something wrong or is this a bug?

Kind regards
Joris

Extend your right margin before plotting and you will be able to see the labels:

par(mar=c(5.1, 4.1, 4.1, 5.1))
plot(as.dendrogram(TestAgnes),horiz=T)
