I'm not aware of a possibility to plot only a part of a clustering
tree. However, you can plot it into a pdf file, for example
pdf(file = "clusterPlot.pdf", width=25, height = 12)
plot(t)
dev.off()
Then look at the pdf file using acrobat reader or similar. Adjust the
width argument if the plot is still too narrow or it becomes too wide.
You can zoom in to see details or zoom out to see the whole picture.
Because pdf is a vector format, plot and font quality is preserved
when zooming in.
HTH,
Peter
