Plot and lm
I want to make a log-log plot with a regression line, but I can't figure
out what I'm doing wrong. What I'm trying is:
plot(mass,area, log="xy", pch=as.numeric(food))
abline(lm(mass~area))
or
plot(mass,area, log="xy", pch=as.numeric(food))
islands$logmass <- log(mass)
islands$logarea <- log(area)
attach(islands)
abline(lm(logmass~logarea))
But that does

Hi all, I checked the archive and didn't see an
anser to this. I updated to Suse 9.2 with kde 3.3
and the installed version of R (from the suse 9.1)
rpms came up with the following failed
dependencies (after querying the rpm)

clients logout .............
You should be able to click Tools/Disconnect Network Drive from a
Windows Explorer window, then select the connection to the Samba server
and click ok. Note, this can be done even if the connection was not
mapped to a drive letter, such as by typing \\server\share in the run
box. You can then map a drive to the server with a different user
account.

repeating matrices in a list
Suppose I have the following square, non-negative matrices
> g=matrix(c(0,2,4,0.25,0,0,0,0.6,0),3,3,byrow=T);
I want to create a list where this matrix is repeated multiple times. if I
do this brute force (manually), using
> env <- list(g,g,g)
works fine. Yields
[[1]]
[,1] [,2] [,3]
[1,] 0.00 2.0 4
[2,] 0.25 0.0 0
[3,] 0.00 0.6 0
[[2]]
[,1] [,2] [,3]
[1,]

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.
script:

Dendrogram for agglomerative hierarchical clustering result
Hey group,
I have a problem of drawing dendrogram as the result of my program
written in C. My algorithm is a approximation algorithm for single
linkage method. AS a result I will get the following data:
[Average distance] [cluster A] [cluster B]
For example:

Asterisk Dry Run
Hi everyone,
I just installed asterisk on my system with the purpose of rerouting calls
on sip channels.
I don't think i need any hardware for that.
I am using LIPZ4(zultys) and sjphone as softphones. I tried setting up both
of them and to call one from the other on the same machine, however could
not.

Elbow criterion plots for determining k in hierarchical clustering
Hi There,
I'm working on some cluster analyses on a large data-set using hclust with
Wards method and Manhattan (city block) distance measures. I've created
dendrograms to illustrate the clustering criteria, but would like to create
a plot to examine for the classic elbow criterion to use in determining the
best number of clusters. Ideally I'd like to plot percent variance

Overlap of leaf labels
Hi,
I have tried looking at the archives but havent found any answer that works
till now (Sorry if i have missed anything)
I am a newbie to R and i am trying to carry out hierarchical clustering
using hclust -> as.dendrogram and then plotting the results as a dendrogram
using the plot function plot(object).
My question is :
In the function "plot", can one decrease the leaf label

Blocking a channel on T1
One of our clients has Asterisk with single T1 card (T100P). T100P gets
only incoming calls. Is there a way to block specific channels (say
channel 9 and 24) so that the Telco does not send calls on those
channels?
Thanks,

dendrogram: how to obtain leaf height
Dear All,
How can the height of a leaf be extracted from a dendrogram?
Sure, I can print it, but I am not able to, say, store it in an object. I think I understand that the height is a property of the split, not the leaf itself, but the printing functions display a "height" or "h" (which changes with "hang") and that is what I want. Obviously, the info is there

newbie: embeding seq in a list
Suppose I want to create a structure containing the following values:
0.8,0.9,1.0,1.1,1.2
If I use
env <- list(0.8,0.9,1.0,1.1,1.2)
then R returns

then R returns

cbind, data.frame | numeric to string?
Complete newbie to R -- struggling with something which should be pretty
basic. Trying to create a simple data set (which I gather R refers to as a
data.frame). So
> a <- c(1,2,3,4,5);
> b <- c(0.3,0.4,0.5,0,6,0.7);
Stick the two together into a data frame (call test) using cbind
> test <- data.frame(cbind(a,b))
Seems to do the trick:
> test

Advice on exploration of sub-clusters in hierarchical dendrogram
Dear R user,
I am a biochemist/bioinformatician, at the moment working on protein
clusterings by conformation similarity.
I only started seriously working with R about a couple of months ago.
I have been able so far to read my way through tutorials and set-up my
hierarchical clusterings. My problem is that I cannot find a way to obtain
information on the rooting of specific nodes, i.e. of

How to: Compare Two dendrograms (Hierarchical Clusterings) ?
Hello all,
I wish to compare two dendrograms (representing Hierarchical Clusterings).
My problems are several:
1) how do I manually create a dendrogram object ?
That is, how can I reconstruct it as an "hclust" object that creates such a
dendrogram, when all I have is the dendrogram image (but don't have the
underlaying distance matrix that produced it) ?
I see that there is a
