Snow parLapply
Dear R-user,
I am trying to use the function 'parLapply' from the 'snow' package
which is supposed to work the same wys as 'lapply' but for a
parallelized cluster of computers. The function I am trying to call in
parallel is 'dudi.pca' (from the 'ade4' package) which performs
principal component analyses. When I call this function on a list of

about cutree
Hi Everyone,
I'm trying to use cutree to get the clusters after hclust. What I used is: mycluster<-cutree(cnclust,h=0.5)
Now, my problem is, how can I get the actual clusters? Thanks!

I'm trying to execute parallel jobs trough library snow on a cluster built

Apache 2.2 + Mod Proxy Balancer + Mongrel - Hot Linking Protection?
Hey guys,
Ok, basically I coded a ruby on rails CMS to manage a bunch of media
files. I am finding that a lot of people are "hot linking" to these
media files and would like to prevent this to save bandwidth. Usually
in the past, it hasn''t been a problem, I would add something like the
following to my .htaccess file

agnes not working
Hello!
I created a distances matrix for 13 objects using daisy (see the attached file).
I am trying to clusteranalyse it using agnes but it's not working.
What might be the problem:
mydistances<-read.csv("Results of daisy.csv")
mycluster<-agnes(mydistances, method="ward")
I am getting:

Calculating First Occurance by a factor
I'm having difficulty finding a solution to my problem that without using a
for loop. For the amount of data I (will) have, the for loop will probably
be too slow. I tried searching around before posting and couldn't find
anything, hopefully it's not embarrassingly easy.

for loop help please!
Hi Everyone,
I have a 2-dim data.matrix(e.g., table1) in which row1 specifies a range of
values. row2 - rown specify the number of times I want to replicate each
corresponding value in row1. I can do this with the following function:
rep(c(table1[1,]),c(table1[X,])) #where X would go from 2 - n.
Now, I can do this manually by changing the values of X and save each
resulting array/vector in

update matrix with subset of it where only row names match
I guess this has a simple solution:
I have matrix 'mat1' which has row and column names, e.g.:
A B C
row1 0 0 0
row2 0 0 0
....
rown 0 0 0
I have a another matrix 'mat2', essentially a subset of 'mat1' where the
rownames are all in 'mat1' e.g.:
B
row3 5
row8 6
row54 7
I want to insert the values of matrix mat2 for column B (in reality it

Strange ! characters inserted into emails
I have never encountered anything like this before, so thought I'd post here
and see if anyone can help.
We have a java application that sends out notification emails to end-users.
The body of the email is some boilerplate text and HTML that is pulled from
a database. When the emails are received there are random instances of " !"

nested 'while' loops
Hi everyone,
I'm using the following code to go over every element of a data frame (row
wise). The problem I am facing is that the outer 'x' variable is not
incrementing itself, thus, only one row of values is obtained, and the
program does not proceed to the next row.
This is the code:
while(x<=coln)
{
while(y<=rown)
{
n<-as.numeric(df[[y]][x]);

[somewhat OT] Apache config for Rails + ColdFusion + PHP

ColdFusion and PHP apps are on an older server, and the Rails apps on a new

Our current setup for the Rails server is Apache2.2 with mod_proxy_balancer

plot(all.effects)
Dear r-helpers,
plot(all.effects()) uses trellis for its output, and often produces
several effect plots in a layout. Can anyone tell me how to set the
arguments to plot.effect which default to
row=1, col=1, nrow=1, ncol=1, more=FALSE
so that I can plot multiple effect plots on one layout?
I was hoping that a call like
last <- rep(c(TRUE, FALSE), c(3, 1))

@cert-authority for hostbased auth - sans shosts?
Hi,
we're looking to reduce the number of host lists that
need to be kept in sync in our system. (There are quite a few of them
all over the place)
OpenSSH CAs are an obvious solution for not having to
keep all host keys in sync in /etc/ssh/known_hosts, however,
while OpenSSH does support using a CA in conjunction with hostbased
authentication,
it still requires a list of all authorized

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
