Hclust question
Hey,
I am running hclust on several different distance matrices and I have a
question thats more about labeling. I've been looking for a way to label
the edge values on the graph with their distances between them. I've
been looking through the documentation and I haven't found anything yet.
Anyone know if there is a way to plot 'hclust' graphs with such edge
values? Or

S's plclust and R's hclust
Hello everyone,
Does anyone know how to implement the argument "unit" in R's plclust
function ? I used to use Splus where this argument exists but it has not
been implemented in R's plclust. The reason why I switched from Splus to
R is that Ward's method is not implemented for S's hclust whereas it is
implemented for R's hclust. What I would need is S's plclust

font sizes for row.names of dendograms
Dear R
I recently performed a cluster analysis. It produced the dendogram no
problem but unfortunately the font size of the row.names were all cluttered
due to their large size
So I tried to change the font size using
plclust(cluster.results, labels=iris$specie, cex=0.8)
and R came back to me saying
Error in plclust(cluster.results, labels = iris$specie, cex = 0.8) :

Similarity matrix
I frequently use hclust on a similarity matrix. In R only a
distance matrix is allowed. Is there a simple reliable
transformation of a similarity matrix that will result
in a distance matrix making hclust work the same as
S-Plus with a similarity matrix? Venables & Ripley 3rd
edition implies that a simple reversal of values
will suffice. Thanks -Frank

hclust and cutree: identifying branches as classes
Good afternoon,
After cuting a hierarchical tree using cutree(), how to check correspondances between classes and branches?
This is what we do:
srndpchc <- hclust(dist(srndpc$x[1:1000,1:3]),method="ward") #creation of hierarchical tree
plclust(srndpchc,hmin=20000) #visualisation
srndpchc20000 = cutree(srndpchc,h=20000) #returns 4 classes
table(srndpchc20000 )

Multiv / hierclust / plclust
I use hierclust (hierarchical clustering) in multiv package. In the
documentation it is said that plclust (plotting a dendrogram) is
available in S-plus. Can I find it anywhere (I have searched through
http://lib.stat.cmu.edu/S and found only quotations of plclust in
multiv) or is it only part of the S package (which I don't have)?
Thanks

trouble with character \u00e2
Greetings R-wizards:
For historical reasons I have filenames with the character "?" and have
successfully used "\u00e2" in its place, with the hoped-for result on all my
on-screen plots.
However since R2.7.0 I have trouble with savePlot() when the file name
includes that character as it does in this example:

Hierarchical clustering using own distance matrices
Hey Everyone!
I wanted to carry out Hierarchical clustering using distance matrices i have
calculated ( instead of euclidean distance etc.)
I understand as.dist is the function for this, but the distances in the
dendrogram i got by using the following script(1) were not the distances
defined in my distance matrices.

probleme with savePlot (to eps)
Hi the list,
I used savePlot to export some eps graph but it seems that the graph
file hold a bug. I include the graph.eps in a LaTeX file. Running latex
is ok. But the dvi file contain some mistake, the graph overprint on
some text and hide it. Then, when I try to convert it to another format,
I get :

Invalid device number in savePlot
Hi,
I recently encountered an error using the command "savePlot" when trying to
save the third of 3 open graph windows. After successfully saving and
closing the first two windows I receive an "Invalid device number in
savePlot" error. The following is copied and pasted from an example session
to illustrate the behaviour:

In the package rtlu, I use the function savePlot. It is convenient since
it let the user decide in which graphic format he wants his graph to be

Usando R CMD BATCH no me funciona savePlot()

savePlot() no longer automatically adds an extension to the filename.
Plaintive squeak: Why the change?
Some OS's and desktops use the extension, so forgetting it causes
trouble. The new default filename keeps a filetype (as before) but the
user now has to type a filetype twice (once as the type, once as
extension) to get the same effect fo rtheir own filenames. And the
extension isn't then checked for consistency with valid file types, so
it can be

Strange behavior of savePlot
Hi all,
I am using savePlot in a loop for saving several graph but I get some
graph in 553x552, some other in 1920x1119. How comes ?
My data are almost all the same (same label, same xlim / ylim, almost
same data. Only the color changes). I save them in bmp.
Thanks for your help.
