Multiple imputations : wicked dataset ? Wicked computers ? Am I cursed ? (or stupid ?)
Dear list,
I'd like to use multiple imputations to try and save a somewhat badly
mangled dataset (lousy data collection, worse than lousy monitoring, you
know that drill... especially when I am consulted for the first time
about one year *after* data collection).
My dataset has 231 observations of 53 variables, of which only a very
few has no missing data. Most variables have 5-10% of

Plotting survival curves after multiple imputation
I am working with some survival data with missing values.
I am using the mice package to do multiple imputation.
I have found code in this thread which handles pooling of the MI results:
https://stat.ethz.ch/pipermail/r-help/2007-May/132180.html
Now I would like to plot a survival curve using the pooled results.
Here is a reproducible example:

MICE for Cox model
R-helpers:
I have a dataset that has 168 subjects and 12 variables. Some of the
variables have missing data and I want to use the multiple imputation
capabilities of the "mice" package to address the missing data. Given
that mice only supports linear models and generalized linear models (via
the lm.mids and glm.mids functions) and that I need to fit Cox models, I

ogginfo: playlength display in milliseconds
Hello
Some time ago I posted a lil' patch to this list which adds milliseconds display of
playlength to ogginfo. Some folks replied that it's plausible and this patch will be
merged to the next version. Vorbistools-1.0.1 got out and the patch is not in it. Why?
Anyway, here's this patch for vorbistools-1.0.1. I hope this time you will include it,

Reentrant NMIs, MCEs and interrupt stack tables.
Hello,
While working on a fix for the rare-but-possible problem of reentrant
NMIs and MCEs, I have discovered that it is sadly possible to generate
fake NMIs and MCEs which will run the relevant handlers on the relevant
stacks, without invoking any of the other CPU logic for these special
interrupts.
A fake NMI can be generated by a processor in PIC mode as opposed to
Virtual wire mode, with a

another missing link in febootstrap; failing tests for libguestfs
After the last round of patches to febootstrap, the image-based test in
libguestfs still failed. It turned out that this happens because Debian
started replacing /var/run and /var/lock with symlinks that point to a
tmpfs mounted to /run. The symlinks were copied to the appliance but
/run/lock did not exist, so pvcreate refused to run (script
'images/guest-aux/make-debian-img.sh').

Control multi-threading in standard matrix product
Hi Ghislain,
I think you might be comparing two versions of R with different BLAS
implementations, one that is single threaded (is your 3.3.2 used with
reference blas?) and one that is multi threaded (3.4.1 with openblas).
Could you check with "perf"? E.g. run your benchmark with "perf record"
in both cases and you should see the names of the hot BLAS functions and

methods package not loaded by default when using Rscript in R2.13
Dear all,
As the object of this mail suggests, the methods package is not loaded by
default in R2.13 when using Rscript whereas it is loaded when using an
interactive session.
An example with the metafor package :
library(metafor)
example(addpoly.rma)
this works in an interaction R shell, but put it in a .R file and use it with
Rscript, it won't work until you added

Control multi-threading in standard matrix product
Hi Ista,
Maybe a little comment in the 'matmult {base}' doc page or on the
'options {base}' in the field 'matprod' would be useful to remind users
to be cautious regarding BLAS multi-threading?
I understand why this is a BLAS related issue and not directly an R
related issue. Nonetheless, my concern was for non-advanced R users,
that may don't even know what BLAS

copying over an existing file when not owner
SuSE 8.2/Samba 3.0.4-SerNet-SuSE
One expects file's owner and date to be preserved
when copying a file to an SMB share. But if a file
with the same name is already there there are two
different ways as to who will ultimately own the
new file and what date will be stamped depending
upon whether the file belongs to the copier or to
someone else.

Control multi-threading in standard matrix product
Dear R Core Team,
I wish to report what can be viewed as a bug or at least a strange
behavior in R-3.4.1. I ask my question here (as recommended on
https://www.r-project.org/bugs.html) since I am not member of the R's
Bugzilla.

product is by default based on BLAS and multi-threaded on all cores

Control multi-threading in standard matrix product
Hi Tomas,
Thanks for your answer.
Indeed, I checked and my R-3.4.1 installed from the ubuntu repository
use 'libopenblasp-r0.2.18.so' while my R-3.3.2 that I did compiled on my
machine use 'libRblas.so' which explain the difference of behavior.
I will use RhpcBLASctl to avoid issue when combining matrix product and
other multi-threading package.

Variables ordering problem in mle() (PR#9313)

Hi,
In the mle() function of the stats4 package, there is a bug in the ordering of
the variables given in the 'start' argument.
By just changing the order of the variables listed in the 'start' list (the

Well, depends on how you want to see it. Under SEV-ES an IRET will not
re-open the NMI window, but the guest has to tell the hypervisor

R 2.11 on Ubuntu 9.10 does not complain abt unexisting objects
Hi
I recently updated to R 2.11 and see a strange problem. When run into
the console, R does not warn when calling an unexisting object, see
below. I don't know if this is related, but I am not able to run the R
CMD BATCH properly... Did someone see a similar problem? Which
information can I provide more on this problem?
Thanks for help!
