dimnames in an array(I'll be grateful if this message will be passed to all list users)
Hello,
I'm hoping someone with a wide experience with R may be able to see
what the program is trying to tell me.
I've got an array:
y1=rnorm(41,0.2)
y2=rnorm(41,0.2)
y3=rbind(y1,y2)
data11<-array(0,c(41,2,2))
data11[,1,]=y3
data11[,2,]=y3
rownames(data11)<-rownames(data11, do.NULL = FALSE, prefix = "Obs.")
colnames=c("V","R")

diagonal matrix, array attributes and how to keep from setting an attribute on "NULL"
Hello,
I've put the short version here and if anyone wants to run the code with
CollocInfer, I've given the full version in the file "analysis".
I come at the question of array attributes and dimnames
to try to simplify.
In a CollocInfer LS.profile analysis using this array 'Y' constructed
as follows:
w=rnorm(41,.05)
z=rnorm(41,.06)
yX<-cbind(w,z)

Formating a zoo dataset .
Suppose I have following dataset :
> head(data1)
Date Return
1 03/31/00 0.14230650
2 04/28/00 -0.03276228
3 05/31/00 -0.06527890
4 06/30/00 -0.04999873
5 07/31/00 -0.01447902
6 08/31/00 0.22265729
Now I convert it to zoo object :
> data11 = zoo(data1[,2], as.Date(data1[,1], format="%m/%d/%y"))
> head(data11)

gluster-volgen - syntax for mirroring/distributing across 6 nodes
NOTE: posted this to gluster-devel when I meant to post it to gluster-users
01 | 02 mirrored --|
03 | 04 mirrored --| distributed
05 | 06 mirrored --|
1) Would this command work for that?
glusterfs-volgen --name repstore1 --raid 1 clustr-01:/mnt/data01
clustr-02:/mnt/data01 --raid 1 clustr-03:/mnt/data01

Nomogram with stratified cph in rms package, how to get failure probability
Hello,
I am using Dr. Harrell's rms package to make a nomogram. I was able to make
a beautiful one. However, I want to change 5-year survival probability to
5-year failure probability.
I couldn?t get hazard rate from Hazard(f1) because I used cph for the model.
Here is my code:
library(rms)
f1 <- cph(Surv(retime,dfs) ~
age+her2+t_stage+n_stage+er+grade+cytcyt+Cyt_PCDK2 , data=data11,

recursive methods for concatenating sets of files
Hello,
I would like to read sets of files within a folder, perhaps using recursive
methods.
Right now, I rename the files before import.
It would be even better to do this without renaming files, without providing
explicit filenames, perhaps by importing files based on chronology,
and translating each filename into a header?
Please excuse my ignorance, and help cure my clunky programming

Why R order files as 1 10 100 not 1 2 3 ?
The code given below worked well. However, the problem is that when I typed
dir1 to see the results I found that R order the files as:
[1] "data1.flt" "data10.flt" "data100.flt" "data101.flt"
[5] "data102.flt" "data103.flt" "data104.flt" "data105.flt"
[9] "data106.flt" "data107.flt"

Using Information from the Stats4 package in base envir
Hi. Thank you very much in advance for your help.
I have generated data from two simple linear models and used k-means
clustering (stats4) to identify two clusters in the generated data.
Next, I would like to do simple linear regression for each separate
cluster. I can do this if I first use the cluster labels to define
two separate data frames with the subset function.
However, I would

formula for calculating the survival probability for nomogram
Hi, I used Dr. Harrell's rms package to make a nomogram.
Below is my code for nomogram and calculate total points and probability *in
original data set* used for building the nomogram. *My question is how I get
the formula for calculating the survival probability for this nomogram. Then
I can use this formula to do validation by using other data set. *

Posix warning : Access to ... is crossing device
I have a distributed/replicated setup with Glusterfs 3.0.2, that I'm
testing on 4 servers, each with access to /mnt/gluster (which consists
of all directories /mnt/data01 - data24) on each server. I'm using
configs I built from volgen, but every time I access a file (via an
'ls -l') for the first time, I get all of these messages in my logs on
each server:
