P2P live migration with non-shared storage: fails to connect to remote libvirt URI qemu+ssh
Migration without --p2p works just fine, ie. the below works:
    $ virsh migrate --verbose --copy-storage-all \
        --live cvm1 qemu+ssh://kashyapc@devstack3/system
    Migration: [100 %]
    Result:
        - On the source host, the guest is shut off
        - On the destination host, the guest is live migratied successfully
Migration with "--p2p" fails, a simple test below:

strange error with rw2010dev
With rw2010dev I get a strange  protect(): protection stack overflow
error with a small data frame which otherwise is usable:
If anybody wants to have a look I can provide an RData file
with the problematic data frame.
Doesn't seem to be necessary, the following simulated example
generates the error:

 > dim(testmat)
[1] 20  4

matrix Manipulation...
Hello everyone,
I have a  2 x 5 matrix: say
0.2   0.3   1   -1   3
0.2.  0.4   5   0.5  -1
I want to replace all the values greater than or equal to 1 with 1 and those
less than or equal to 0 with 0. So I should end up with a mtrix looking
like:
0.2   0.3   1   0   1
0.2.  0.4   1   0.5  0
Any ideas how to do this?

Migrating guests
Hi,
I'm experimenting with the migration function of virsh. I'm doing the migrate with following commands:
virsh migrate --life --persistent --copy-storage-all --verbose --abort-on-error domain qemu+ssh://root@destination/system
virsh migrate-setmaxdowntime domain 20000
However sometimes at the end of the migration, the guest isn't started on the destination host. So I'm left

dmultinomial
Hello All,
I'm trying to run a maximum likelihood analysis using dmultinomial (i'm
avoiding dmultinom as I'd like to run it with vectors for the ML stuff).
 However, I'm having a hard time getting even the simplest example
running.  Any help would be greatly appreciated.

kmeans and plot labels
Hi,
Thanks Sarah. Unfortunately I did not get a step further.
My question, perhaps a bit clearer, is how to display the case control status (or any other arbitrary point label) after clustering in a plot:
With a bit of pseudo code, where dataset is a data.frame, parameters are those column names where we find numerical values (no NAs) and nclasses is the desired number of classes.

Conditional looping over a set of variables in R
Here's the problem I'm trying to solve in R: I have a data frame that consists of about 1500 cases (rows) of data from kids who took a test of listening comprehension. The columns are their scores (1 = correct, 0 = incorrect,  . = missing) on 140 test items. The items are numbered sequentially and are ordered by increasing difficulty as you go from left to right across the columns. I want

descriptive statistics
Hi. In a data set I have a variable that takes values from 1 to 14. For each
subgroup of values of this variable, I would like to obtain some descriptive
statistics of other variables present in the data set. I've been trying with
a "for" loop but I couldn't get nothing. Could you please suggest me some
lines?

nth step transition matrices
Hello,
I have a question in regards to markov chains and transition
probabilities.
I am trying to figure out a way to calculate the "kth-step transition
matrix" of a given matrix.
Say for example I have a single step 2x2 matrix:
           1     2
P= 1  .95 .05
       2  .01. 99
If I were to convert this matrix to a 2-step transition probability
matrix I would get:

transposing a list of vectors
I have a list of vectors, all forced to be the same length:

  cell.fill=c("red","blue","green"),
    back.fill=rep("white",3),
    scale.max=rep(100,3)
    )

Trouble passing list or non-list to function using ...
Hello,
Simply put, I'm trying to call a function "testme" with value "age=NA".   I wish to use "dotlist<-list(...)"  inside the function and have dotlist become:
$age
[1] NA
I'm modifying existing code and need to minimize changing that code so it's easiest to conform 
how I call the existing function.

deparse(substitute(x)) on an object with S3 class
Dear list,
can someone explain to me why deparse(substitute(x)) does not seem to work
when x is of a user-defined S3 class?
In my actual problem, my print method is part of a package, and the method
is registered in the NAMESPACE, if that should make a difference.
> print.testclass <- function(x,...){
  xname <- deparse(substitute(x))

How to use a for loop to generate two sequences
Hi R users,
Hope the question is not too simple:
How to use a for loop to generate two lists as below:
testlist <- list(test1, test2, ..., test1000)
stringlist <- list("test1","test2",...,"test1000")
Thanks
