R help - Nov 2003 - hidden node names in a dendrogram plot

HI All:

When I plot a cluster (from hclust(...)) or a dendrogram
(as.dendrogram(hclust(....)), the node names are partly cut off at the
bottom of the plot.
Is there any way of resizing my cluster plot so that we can see them all?

Thanks in advance.

Karthi.

Yes, if you increase the corresponding margin (1-st or 4-th),
see ?par , e.g.,

data(USArrests)
dhc <- as.dendrogram(hc <- hclust(dist(USArrests), "ave"))
par(mar=c(3,2,2,6))
plot(dhc, horiz=TRUE)
