plot.dendrogram() plot margins
Hello,
Is it possible to remove those extra margins on the "sample" axis from
plot.dendrogram:
par(oma=c(0,0,0,0),mar=c(0,0,0,0))
ddr<-as.dendrogram(hclust(dist(matrix(sample(1:1000,200),nrow=100))))
stats:::plot.dendrogram(ddr,horiz=F,axes=F,yaxs="i",leaflab="none")
vs.
stats:::plot.dendrogram(ddr,horiz=T,axes=F,yaxs="i",leaflab="none")

Plotting horizontal dendrograms
I am using hclust and plot to produce dendrograms. Using my input data I am
able to complete an analysis and obtain a vertical plot.
I want to be able to plot the dendrogram horizontally.I am using version 2.6
of R and have updated my packages recently.
Using the sample script for dendrograms I can produce a horizontal plot
using the instruction horiz = TRUE in plot().

Drawing dendrogram
Dear all,
I would like to draw a dendrogram and mark some parts/branches (by using "segments") including their labels. If I draw it without specifying the length of x axix, I am able to do that (as in My dendrogram 1 of the following codes). However, if I want to specify the x axix, I am not able to draw marking line (by using "segments") including labels (as in My dendrogram

plot.dendrogram xlim/ylim
list(...),
I would like to zoom in to the leaves of large trees in a dendrogram
plot. The playwith package allows zooming by passing xlim and ylim
arguments to the plot call (Hmisc does this too I think). But
currently stats:::plot.dendrogram does not accept xlim or ylim. So I
would like to enable that. In place of the existing code chunk:
xlim <- c(x1 - 1/2, x2 + 1/2)
ylim <- c(0,

Interacting with dendrogram plots, locator() or click()
I would like to explore dendrogam plots interactively. For example, click on a node and return information about all of the children of that node.
Is there a high level wrapper for locator() or click() that will return the nearest dendrogram node on a plot?
If not, is there a way to obtain the [x,y] coordinates of all the nodes on a plot?
Thanks,

Coloring leaves, twigs and labels in plot.dendrogram()
Core developers,
I couldn't find any simple way to send a vector of colors to apply to each
terminal in plot.dendrogram() or plot.hclust()---I asked R-help about it a
few weeks ago and didn't get any response---so I hacked that functionality
into the plot.dendrgram code (see below for hacked function plus
examples)....
Is there any chance this functionality could be added to the

graphic of hierachical clustering
Hi all,
I would like to save the dendrogram of a hierarchical clustering.
Let reshc the result of the fucntion hclust(). To save the dendrogram,
I can use the function postscript:
postscript(file="hc605.ps")
plot(as.dendrogram(reshc),horiz=T,ylab="",main=" ")
dev.off()
Using the functions plot and as.dendrogram, it is possible to obtain an

Formatted Data File Question for Clustering -Quickie Project
I am trying to learn how to format Ascii data files for scan or read
into R.
Precisely for a quickie project, I found some code (at end of this
email) to do exactly what I need:
To cluster and graph a dendrogram from package (stats).
I am stuck on how to format a text file to run the script.
I looked at the dataset USArrests (which would be replaced by my data
and labels) using UltraEdit. That

Dendrogram labels
Is there any way to change the orientation of the labels on the end of the dendrograms to horizontal rather than vertical? If so, how can I do that.

Plotting hclust with lot of objects
Hi!
I am newbee to R and I am facing the problem in plotting
the dedrogram with lot of objects. The lines and labels are overlapped very
badly, and writing the graphic to postscript and zooming there is not helping
either. I tried cut.dendrogram method, but getting the error that it doesn't
exist even though I get the man pages for it.
I would not find any solution in web as well, and I

Dendrogram plotting options?
Hi, I was wondering if there is more flexibility in the output of
dendrograms when plotting a hclust object. I can't seem to find
information on how to change the default output of a "hanging" style
tree with the axis on the right to a left-to-right plot with and axis
on the bottom. Example code follows:

lattice levelplot axis + custom annotations
How would I set the "scales" property of a lattice levelplot, so that
I can add specific annotations at specific positions?
For example, I have a 200 x 1000 element levelplot. Along the y-axis
(along the 1000-element axis) I would like to add annotations on the
left side of the levelplot at elements 120, 300, 500, and 805, which
represent clusters of interest.

Bug in plot.dendrogram, and how to submit patches
Hello,
Before submitting a bug report, I thought I would ask here, as
recommended in http://www.r-project.org/posting-guide.html.
Using R 2.8.0 under Mac OS X, I find that edge labels are misplaced
when doing plot.dendrogram(..., horiz=TRUE), for example

dendrogram rect.hclust() not working?
I have tried to use rect.hclust() to draw a rectangle around a set of
leaves, but am running into trouble.
The rect.hclust() is drawing two rects instead of one, and of the
wrong size:

scoreClusterObj <- hclust(scoreDistanceObj, method=clustMethod)
order <- scoreClusterObj$order
orderedLabels <- rep(0, length(order))

Help with hclust() and plot()
Hi
When I use plot(hclust(dist..)...)...) etc to create a dendrogram of a
hierarchial cluster analysis, I end up with a vertical tree. What do I
need to do to get a horizontal tree?
Also, my users are used to seeing trees who's leaves all "end" at the
same place (eg. Like in minitab). Is this possible in R?
Thanks

Hi all, Hi Gavin,
thx for your help i finally found out what i want to do and how to
fix it.
just needed to get some more level my cut level was too small...
two question remain...
a) can i somehow scale the twigs after cutting ?
b) how can i label the nodes and how to label which one...

how to colour labels (each label with a colour) in a dendrogram?
Hello to all,
I still have this doubt.
I'd like to colour the different labels of my dendrogram each one with a
different colour. How can I do? I guess I could do using *edgetext* and
then *t.col* or* lab.col* but I don't know how to add edgetext to my
dendrogram. Can you help me please?
Example:

using an image as a dendrogram label
Hi, does anybody know if it is possible to use an image (rather than
text) to label the leaves of a dendrogram? I realize that this will
not always lead to a useful on-screen display, but ideally I'd like
to directly go from the dendrogram to a PDF and on-screen viewing is
not to too important for me. Also, my trees are relatively small.
Any pointers would be apreciated

neatmap - draw.dendrogram - help!
Hi all,
I'm having a problem where by I'm trying to use the NeatMap draw.dendrogram
function as it is more versatile in placement/direction of dendrograms,
instead of the limited plot function.
Using plot I can get my dendrograms to display the species name for each
leaf of the tree. But I cannot figure out how to make this happen using
draw.dendrogram..
