Package fechner for Fechnerian scaling, on CRAN now
Version 1.0-0 of fechner has been released to CRAN.
Fechnerian scaling of discrete object (or stimulus) sets provides a
theoretical framework for deriving, so-called Fechnerian, distances
among objects representing subjective dissimilarities. A Fechnerian
metric on a set of stimuli is constructed from the probabilities with
which the objects are discriminated from each other by a

The best way to protect against starvation?
Hello,
If an ordinary user runs:
-- snip --
cat > starv.c <<EOF
main(){ char *point; while(1) { point = ( char * ) malloc(10000); }}
EOF
cc starv.c
while true
do
./a.out &
done
-- snip --
This will fast starv the operating system (FreeBSD 6.2). I have tried to
limit the number of processes and the amount of memmory consumed (in
login.conf).
There is also a file /etc/malloc.conf

Response to R across the university
This email isn't asking for assistance, but I thought R-help readers
would find it interesting. This week we offered a half-day
introduction to R for researchers at Augsburg University. The
response was astonishing. Although Augsburg has no medical faculty
and no engineers, there was far too much demand, with interest from
every faculty (barring theology, "for one small

R-1.8.0 + IBM VisualAge/C for AIX compiler
A while ago I compiled R 1.7.0 for AIX (with the above compiler - I'll
call it xlc) and I was surprised that it went quite smoothly.
Unfortunately with R 1.8.0 it's not as easy, but I succeeded at least
partially. Static R works fine (after some tweaking), but
--enable-R-shlib fails resp. produces a buggy R. Following are the
problems I encountered (in a warning-to-fatal-error

Catching R's (D)COM output in perl
Hi,
i'm using Perl to control R under Windows via the Win32::OLE module and
R's (D)COM server. This works fine, if i send commands and/or simple
data structures to R. I am also able to get matrix-shaped return values
into my Perl program, like this
# snip ----------------------------------------------------
my $R = Win32::OLE->new('StatConnectorSrv.StatConnector');

R outside of universities
R has spread far and wide with great success. It is not only used
extensively in universities, but also apparently in governmental
organisations and in industry. As the recent discussion of R's Pros
and Cons shows, there are many reasons for this. It would be
interesting to know just how widely R is used, where it is used most
(and where least or not at all). Does anyone have a

R's DYLD_LIBRARY_PATH override problems on Mac OS X
In Mac OS X native version: The R shell wrapper (bin/R) overrides
default library search path with DYLD_LIBRARY_PATH and adds (among
others) /usr/X11R6/lib. This causes problems when modules need
(directly or indirectly) libraries from Apple's frameworks which are
masked by X11. Examples for such packages are SJava and RGL. SJava
needs JavaVM which in turn loads OpenGL framework. RGL

Xen, IRQ-sharing and PCI passthrough
Hello,
I''m seeing problems with Xen and IRQ-sharing PCI cards which are passed
through to a Xen DomU. As I''m not sure whether this is a problem with
Xen or with the Debian Xen Kernel (2.6.26-13 from lenny) I''m using, I''d
like to ask here before posting a bug.
Reproducing the problem goes as follows:

Kendall's tau-c
Hello,
I can't find a package which calculates Kendall's tau-c. There is the
package Kendall, but it only calcuates Kendall's tau-b.

about REPL and loops in general ...
I need to implement some external callbacks to R and I'm not happy with
the current REPL, since it prevents any general solution.
Are there plans to improve the current REPL anytime soon? The current
approach has some deficiencies you are surely aware of (only one input
(=external event loop), the loop is blocked while waiting for input in
R_ReadConsole, ...). But the major problem is

linking to R.dll on Win32 - issues with recent MinGW?
I encountered several strange issues when linking to R.dll on Windows
and I wonder if anyone of the Windows savvy-folks here had seen some of
the issues before and have some explanation.
My Rserve links to R dynamic library. That works perfectly on unix
boxes and worked fairly well with older MinGW and older R (<=1.7.1).
What I do in fact is that I specify
-L$(R_HOME)/bin -lR
when linking.

Danish callerid on a x100p card
Hi
I've got a cheap card from x100p.com for my pots line. I haven't found a
definate answer if it is possible to get danish(DTMF without signaling
before it). I have had a look at bug #9 but that is
written longtime ago.
I am running zaptel 1.4.7 and asterisk 1.4.14 BRIstuffed 0.4.0-test4 both
from the xorcom debian packages. I believe they should contain some kind

AW: Xen, IRQ-sharing and PCI passthrough
Florian,
I read already here and there that you shall not use shared interrupts in different PV DomUs,
although I never found a written statement. But behaviour is exactly as you described, thus
I took care that cards that share an IRQ are in the same DomU/Dom0. I also selected my
motherboards accordingly.
When I lately discussed lately with someone about MSI, I had the hope this could help,

R as OS X Framework
After the recent discussion about future direction of the Mac OS X
port, I was toying with the idea to make R a proper Mac OS X framework.
There are several advantages: OS X locates frameworks automatically,
therefore any program wishing to link against R has only to specify
"-framework R" at link time. Furthermore versioning is supported, i.e.
if a program is linked against R 1.7.1

ssh in small devices
Dear Sirs,
This must have been asked before but I don't find and FAQ around
dealing with the issue.
We are building small devices that connects to Internet (www.ipio.nu).
The next generation of this we
want to base on AVR32 and run a small slimmed version of Linux. We
have som program on this device that
we want to connect to servers out on Internet. SSL seems to be "quite

Re. When is *interactive* data visualization useful to use?
Hello Tal,
You asked *When is it helpful to use interactive plots? Either for data exploration (for ourselves) and data presentation (for a "client")?*
My answer: It's helpful for checking data quality, for exploration with and without "clients", for checking results, and for data presenting.
Notes:
