Problems with "predict" function
Hello,
I am synthesising some sales data over a twelve month period, and then trying to
use the "predict" function, firstly to generate a thirteenth month forecast with
upper and lower 95% confidence limits. So far so good
But what I then want to do is add the upper sales value at the 95th confidence
limit to the vector of thirteen months and their respective sales to create a

extracat , JGR, iWidgets install problems
[Environment: Win XP, R 2.10.1]
I'm trying to install the packages JGR and iWidgets required by the
extracat package to make the interactive plots
in the package work. I've tried various things, but nothing seems to
work. Here is my most recent attempt,
followed by my sessionInfo().
Does anyone have any suggestions how to make this work?

Improve hot cold splitting to aggressively outline small blocks
Hi Teresa,
Thank you for your reply! I discussed this with Aditya and Rodrigo today
about this. We will always have PGO turned on for our benchmark, (i.e. we
assume the profiling information is always available). In terms of the
workload we supply to PGO: For postgresql, I suggested we use the "pgbench"
benchmark, a TPC-B-based SQL benchmark for postgres, to supply profiling
information

no labels when plotting dendrograms
I'd like to be able to cut dendrograms at a height I specify
and then plot the resulting subtrees. I wanted to use the
dendrogram object for this purpose because there doesn't seem
to be a canned way to cut a hclust object and get a list of
hclust objects, but there is a function (cut) that does that
for dendrograms. The problem I'm having is that when I plot
a dendrogram, I

Dial plan questions

Many improvements and a few problems
Hi,
I must say I'm very impressed with improvments in the latest versions of
the encoder, especially in 2-pass mode. I was trying encodes of videos
with sudden changes from no or moderate motion, to high motion scenes.
Most samples of Theora quality I saw on the net were very slow motion
usually. These high-motion videos were especially hard for Theora and it
quickly introduced

Problems with "predict" function ii
I have realised that I should have used "detach" before attaching another
dataframe, but even when I do this it's still giving me lots of lines, rather
than just one:
My code:
m<-runif(1,0,1)
m
mres<-m*(seq(1,12))
mres
ssd<-rexp(1,1)
ssd
devs<-rep(0,length(mres))
for(i in 1:length(mres)){devs[i]<-rnorm(1,0,ssd)}

Cambiando limites en hclust()
Buenas tardes a todos,
Estoy interesado en cambiar los límites del eje y en un dendograma
construído utilizando la función hclust(). A continuación un ejemplo:
hc <- hclust(dist(USArrests), "ave")
plot(hc)
Hasta aquí todo bien. Si quisiera cambiar los límites del eje "y" de c(0,
200)? Al usar
plot(hc, ylim = c(0, 200))
no observo efecto alguno.
Qué puedo hacer?

clustering problem
Hi,
I have a gene expression experiment with 20 samples and 25000 genes each.
I'd like to perform clustering on these. It turned out to become much faster
when I transform the underlying matrix with t(matrix). Unfortunately then
I'm not anymore able to use cutree to access individual clusters. In general
I do something like this:
hc <- hclust(dist(USArrests), "ave")

how to colour labels (each label with a colour) in a dendrogram?
Hello to all,
I still have this doubt.
I'd like to colour the different labels of my dendrogram each one with a
different colour. How can I do? I guess I could do using *edgetext* and
then *t.col* or* lab.col* but I don't know how to add edgetext to my
dendrogram. Can you help me please?
Example:
require(graphics); require(utils)

Manually modifying an hclust dendrogram to remove singletons
Dear R-Help,
I have a clustering problem with hclust that I hope someone can help
me with. Consider the classic hclust example:
hc <- hclust(dist(USArrests), "ave")
plot(hc)
I would like to cut the tree up in such a way so as to avoid small
clusters, so that we get a minimum number of items in each cluster,
and therefore avoid singletons. e.g. in this example, you can see

"cophenetic" function for objects of class "dendrogram"

dendrogram branches with different lty
Dear r-list,
I am trying to visually seperate the two main clusters of a dendrogram.
The idea is to use:
'edgePar=list(lty=3)' for 'dend1[[1]]' and
'edgePar=list(lty=1)' for 'dend1[[2]]'
I have not found a way to solve this. Any suggestions?

Help with hclust() and plot()
Hi
When I use plot(hclust(dist..)...)...) etc to create a dendrogram of a
hierarchial cluster analysis, I end up with a vertical tree. What do I
need to do to get a horizontal tree?
Also, my users are used to seeing trees who's leaves all "end" at the
same place (eg. Like in minitab). Is this possible in R?
Thanks
Mick
