Performance issues with R2.15.1 built from source on Solaris
Is this a SPARC system? On at least some SPARC systems, the "long double"
type in C is implemented very slowly in software, and it seems that it is
used for the sums done when calculating standard deviations with "sd".

Installing R2.15.1 on ubuntu
Per the suggestion of this list when I posted on the r-help list, I have
gone to cran, linux downloads and read the read me file to try and install
the binary for R 2.15.1 on my ubuntu AMD64 machine. I added to my
sources.list the deb http:\\cran.wustl.edu\bin\linux\ubuntu precise main .
Then I ran sudo apt-get update and sudo apt-get install r-base. The system
promptly installs R 2.14.1 . I

Compiling R2.15.1 on ubuntu with x86-64 architecture and shared library
I am sure I am providing insufficient information, please ask for more.
I installed R 2.14.2 on my Ubuntu laptop with and AMD64 processor and also installed RStudio and everything worked fine.
Now, I tried to build R 2.15.1 from source and installed it using defaults. RStudio now complained that R was not built as a shared library.
Went back and uninstalled, and configured with -enable-R-shlib

Question about R performance on UNIX/LINUX with different memory/swap configurations
Does anyone have any guidance on swap and memory configuration when
running R v2.15.1 on UNIX/LINUX? Through some benchmarking across
multiple hardware (UNIX, LINUX, SPARC, x86, Windows, physical, virtual)
it "seems" that the smaller memory machines have an advantage.
Typically my organization builds their UNIX servers at a 1:1 physical
memory:swap configuration. We plan on running

Question about R and multiple CPU's
I have a question about multiple cores and CPU's for running R. I've
been running various tests on different types of hardware and operating
systems (64 bit, 32 bit, Solaris, Linux, Windows, RV.10, .12, .15,
.15.1.) Generally speaking, it seems that for a single user and process
that R prefers to have as much resources as possible; especially memory.
I've looked at some of the r-sig

Samba 3.0.25 plugin changes
Greetings,
Before I start digging into making our local passdb plugin work with Samba
3.0.25, is there any heads up I need to know about?
I tried to compile the example plugin in samba-3.0.25/examples/pdb, but it
fails. See below for a sample of the error messages.
If I try to compile the same example that comes with Samba v3.0.24, the
example code compiles without any issues?

Hello Rxperts..
I have a peculiar situation.. XML library is not available with R2.15.1
whereas I was able to install it with R version 2.13.1. Would highly
appreciate your suggestions. I am now trying to see if XML works with
previous versions of R.

timeBasedSeq stumbles over the year 2038 (xts package)
I have the following problem:
As expected I obtain
timeBasedSeq( 2037/2037)

However if I do the same for 2038 I get
timeBasedSeq( 2038/2038)
[1] "2038-01-01" "2039-01-01"
I get the same strange result if I use later years or any interval that contains 2038:

Where is the R configuration file or how to override R compilers
I have a question about how one can modify or override the compilers
that R uses for package installations? Or if perhaps this configuration
is in some editable file somewhere.
Initially I built the version of R 2.15.1 on Solaris SPARC (virtual T4),
but found out the build was done as 32 bit. After some research, I
found that the pre-compiled GCC version I had only allowed for 32 bit.

logistic regression
Hi
I am working on corpora of automatically recognized utterances, looking
for features that predict error in the hypothesis the recognizer is
proposing.
I am using the glm functions to do logistic regression. I do this type
of thing:
* logistic.model = glm(formula = similarity ~., family = binomial,
data = data)
and end up with a model:

Regression in kernel 3.5 as Dom0 regarding PCI Passthrough?!
Hi!
i notice a serious regression with 3.5 as Dom0 kernel (3.4 was rock
stable):
1st: only the GPU PCI Passthrough works, the PCI USB Controller is not
recognized within the DomU (HVM Win7 64)

R2wd package wdGet() error
I am having trouble using the R2wd package. The last time I used it
successfully, I was running an earlier version of R and an earlier version
of Word with an earlier Windows OS. I'm not sure which if any of these
changes might be contributing to the problem. Right now I'm using
R version 2.15.0 (2012-03-30) for Windows

OT: computing percentage changes with negative and zero values?
Dear all
I need to compute percentage changes of my data, but unfortunately
they contain both negative and zero values, and I am quite confused on
how to proceed. Searching the internet I found that many people ran
into similar issues, with no obvious solution available.
The last couple of weeks I've been playing with all the data
transformations that I could think of. Below I will expose on

smbpasswd produces INCORRECT sambaNTPasswd hash on ppc (yellowdog 4.0 on xserve G5)
I'm having trouble setting up samba as a PDC on an apple xserve, using
yellowdog linux 4.0. After a lot of thrashing, I believe the problem
may be smbpasswd generating the wrong NT hash. Running smbpasswd on a
redhat box (intel architecture) produces the follow LDAP entry:

objectClass: top

Loess with more than 4 predictors / offsets
Hello,
Does anyone know of an R version of loess that allows more than 4
predictors and/or allows the specification of offsets? For that matter,
does anyone know of _any_ version of loess that does either of the
things I mention?
Thanks,
