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:

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

hclust() memory issue
Hi, I have a microarray dataset of dimension 25000x30 and try to clustering
using hclust(). But the clustering on the rows failed due to the size:
> y<-hclust(dist(data),method='average')
Error: cannot allocate vector of size 1.9 Gb
I tried to increase the memory using memory.limit(size=3000), still got the same
error.
I also tried agnes() from cluster package and pvclust() from

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,

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

NAs produced by integer overflow, but only some time ...
I have problem with integer overflow that I cannot understand.
I have a character vector curr.lemmas with the following properties:

That vector is the input to the following function:

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.
library(pvclust)
pvc <- pvclust(matrix, nboot=1000)

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",

Hi there,
I have been trying to use the "pvclust" package but have been having
some difficulties. This is the first time I have used R so I am sure the
mistake I am making is a basic one. The data I have is a distance matrix
and I have been using the command; fit <- pvclust(cluster, nboot=1000,
method.dist="euclidean") to try and perform hierarchical clustering with

NAs produced by integer overflow, but only some time ...
a) Numeric values may be either integers (signed 32 bit) or double precision (53 bit mantissa).
b) Double precision constants are numeric with no decoration (e.g. 61224). Integer constants have an L (e.g. 61224L).
c) 61224*61224 > 2^31-1 so that answer cannot fit into an integer.
d) Exponentiation is a floating point operation so the result of 61224L^2L is a floating point answer that CAN

predict.lrm vs. predict.glm (with newdata)

I have run into a case where I don't understand why predict.lrm and
predict.glm don't yield the same results. My data look like this:
