approxfun-problems (yleft and yright ignored)
Dear all,
I have run into a problem when running some code implemented in the
Bioconductor panp-package (applied to my own expression data), whereby gene
expression values of known true negative probesets (x) are interpolated onto
present/absent p-values (y) between 0 and 1 using the *approxfun -
function*{stats}; when I have used R version 2.8, everything had
worked fine,

pvclust crashing R on Ubuntu 10.10
Hi all
I am writing to you with a question regarding the pvclust package. And
yes, before the usual people produce their usual
contact-the-package-maintainers line, ye, I tried that but the emails
one can find on the web either bounce or are not responded to. Also,
yes, this error has already been reported as a bug but been shot down
as not reproducible

GridR error
Hi,
I am trying to use 'GridR' package for the first time, and I'm running
into a strange error from grid.check:
> grid.check(gridFun)
Error in exists(add) : invalid first argument
After playing around in recover mode, I see that this because the
variable 'add' created by grid.check is blank:

p-values pvclust maximum distance measure
Hi,
I am new to clustering and was wondering why pvclust using "maximum"
as distance measure nearly always results in p-values above 95%.
I wrote an example programme which demonstrates this effect. I
uploaded a PDF showing the results
Here is the code which produces the PDF file:

p-values with pvclust
Hi,
if you look at the first image (Image1) you see that there are 2 main
clusters 7 and 8
I wanted to use pvclust to calculate a p-value whether these clusters are
due to chance
or statistically significant. Unfortunately pvclust does not provide a
p-value for the first
brunch (7 and 8).
So I added a row to my matrix which is very different to the rest of the
data to create an additional

pvclust Error:NA/NaN/Inf in foreign function call (arg 11)
Hi all,
I'm new to R and I'm struggling to decipher an error message. Briefly, I am trying to use the pvclust package to do hierarchical clustering of some CGH data. The data is from the Progenetix CGH database. It is arranged as a table where each column is a single case and each row is a single chromosome band. The value in each cell is either 0, 1, 2, or -1. Corresponding to no change,

Split PVClust plot
Dear All
I'm using PVClust to perform hierarchical clustering, for the output plot I can control most of the graphical I need, however the plot is large and I would like to split it vertically into two panels one above the other. Is there a way to plot only part of a PVClust plot, I tried to convert it to a dendrogram with
result2 = as.dendrogram(result)
however I get the error message

Node colors in pvclust
Is there a way to assign color to nodes as with
hclust/as.dendrogram/dendrapply when using pvclust?
The problem is that as.dendrogram isn't working on the pvclust objects.

Fwd: RE: pvclust function
You should reply to the list, not just me, and even more because I
cannot really help you!!
My guess (but I don't know this package, and even less this function) is
that pvclust() is expecting a matrix as the first argument. However,
"cluster" is no data, it is a function. Why, I don't know. Take a closer
look at ?pvclust, especially the "usage",

hvcluster() with distance method from vegdist(), package = vegan
hello,
i'd be happy if someone could provide help with the following problem:
i have a dist.matrix that comes from vegdist() function of the vegan
package. the used method = "horn" is not accepted as argument in
hvcluster(...,dist.method="...").
is there a way to incorporate the method "horn" in hvcluster()?
thanks in advance!

pvclust missing values problem
Hello all,
I posted a question to this list last week and received no response. I am unsure if this means no-one knows the answer or if I posed the question badly. I'm going to assume I posed the question badly and try again. I am new to R so it is quite likely it's a very naive question, however if there is something blindingly obvious that I am missing or if there is another resource I

pvclust:a general and a specific question
I realize questions about packages should go to the package maintainer,
but perhaps I have an old email address (suzuki3 at is.titech.ac.jp)
Also I have both a general, and a specific, question.
1) General question: i've used pvclust before to assess significance of
clusters and got reasonable results. However, on a new data set (see
below) the results seem odd. I wonder if pvclust is a

pvclust distance matrix
Hello,
I am attempting to assign significance levels to a UPGMA cluster analysis as part my doctoral research. The pvclust function works well but doesn't include the similarity index I need (morisita's) as an option for computing a distance matrix. Morisita's is available in vegdist in the VEGAN library but I am having a hard time getting the vegdist function to "direct

pvclust
Hello there,
Here's a question regarding p-values on clusters produced by hierarchical
cluster analysis. A web search led me to the program pvclust to tackle this
problem. But when I run the problem I get strange results. The 'AU'
(approximately unbiased) p-values are very different from the 'BP' values
(ordinary boot-strap) p-values. The AUs commonly are in the 80-100

reorder always returns "ordered"
Or at least is seems that way to me. It's not a big problem, but the
behavior doesn't match the documentation. (I think r-help is the
place to report this. )

> x.ro <- reorder(x, rnorm(5))

How to do clustering
Dear List,
I have another question to bother you about how to do clustering.
My data consists of 49 columns (49 variables) and 238804 rows.
I would like to do hierarchical clustering (unsupervised clustering
and PCA). So far I tried pvclust (www.is.titech.ac.jp/~shimo/prog/*pvclust*
/)
but I always had the problem like for R like "cannot allocate the memory".

clustering of binary data
Good morning,
I am analyzing a dataset composed by 364 subjects and 13 binary variables
(0,1 = absence,presence).
I am testing possible association (co-presence) of my variables. To do
this, I was trying with cluster analysis.
My main interest is to check for the significance of the obtained clusters.
First, I tried with the pvclust() function, by using method.hclust="ward"

Replacing several rows of a matrix at once
Hello Folks. This must be a silly question with a (not) obvious (to me)
answer.
Consider this:
tmp <- matrix(1:200, nrow = 20)
vec <- 300:309
tmp[9,] <- vec # replacing one row works fine
p <- c(3, 11, 17)
tmp[p,] <- vec
# replacing multple rows pastes the values down a column and recycles vec.
What I want to do is replace multiple rows simultaneously at once. I
suppose I can
