graph algorithms in R
Hi,
I was wondering if there are any packages available that can represent
mathematical graphs along with functions to manipulate them? Google
did'nt turn up anything ( I may be asking too much of R :-/ )
Thanks,

association rules in R
Hi
I am interested in data mining problems. Has anybody ever programmed and
worked with association rules in R?
I am very grateful for any hint.
Best regards

building a package under windows
Hi,
I have a package of my own which seems to work fine under linux.
I want to make a compiled version for windows.
(I work with windows 2000 and R 2.0)
I have followed the steps described in the file
readme.packages (in the top-level directory of the binary installation)
and I had a trouble at this step (which aim is not documented):
C:\Program Files\R\rw2000\src\gnuwin32>make libR.a

Asterisk Dialplan command "PPPD" released
Hello all!
Sirrix AG, Saarbr?cken (manufacturer of the Sirrix.PCI4S0 4-port ISDN
card for Asterisk) has released the new Asterisk dialplan command PPPD
(app_pppd). It allows to connect a Linux PPP daemon to an arbitrary
digital (ISDN) Asterisk channel to provide RAS dialin and dialout.
The PPPD command has successfully been tested with Sirrix.PCI4S0 cards
and a standard ISDN4Linux ipppd "on

ps-output and LaTeX/DVIPS/PS2PDF - Greek letters disappear
Hello!
My graphs are produced using the "postscript"-option in R (R version
2.10.1 (2009-12-14)). When Greek letters are used on the axis,
everything looks fine in the *.ps-file. If included in a LaTeX-file and
(on Ubuntu 10.04, fresh install), the Greek letters appear in the DVI-
and PS-output, however, if converted with ps2pdf they suddenly
disappear. Could anyone suggest a

plot & xlim/ylim & range of axis
Dear mailing list readers!
Using R and the plot function I stumbled over this little issue:
plot(x=NULL,
y=NULL,
xlim=range(1:10),
ylim=range(1e-9:1),
log="y")
produces an plot empty plot, where the y-axis is in the specified range.
Changing ylim to
ylim=range(1e-9:1e-3)
creates an y-axis in the range of 1e-12 to 1e-6. This appearance of the
y-axis is a

Does anything change if you use the development version of Rdpack (not
currently on CRAN)? Apparently, the latest commit performs some

False positives in check for lost braces (in tools::checkRd())
This is a known issue already reported to the Rdpack maintainer. In some
cases, the Rd code generated by Rdpack's macros contains unnecessary
braces that trigger the check note because they match the pattern
"text{text}" that detects common mistakes like "code{x}" (missing an
escape for the macro name).
Rdpack's fork of tools::deparseLatex() is being updated to

Summer of Code, LLVM, parallelization and R
Hi everybody,
I'm currently working towards my Master's degree as a student of
Computer Science at the University of Saarbr?cken and highly
interested in compiler construction, interpretation techniques,
optimization, programming languages and more. :)
Two professors of my university approached me about an interesting
project just a few days ago: Developing a LLVM-based JIT

Plot of a subset of a data.frame()
Hello,
my data.frame is sort of a collection of process values, i.e. huge
run-chart. It consists of a time-stamp in the first column (date as
string), factors in the following columns (used for subset-filtering),
and some process-data columns.
Hereafter, two examples are listed, showing the problems that occour
during print:

R_CheckUserInterrupt() can be a performance bottleneck within GUIs
tl;dr: R_CheckUserInterrupt() can be a performance bottleneck
within GUIs. This also affects functions in the 'stats'
package, which could be improved by changing the position
of calls to R_CheckUserInterrupt().
Dear all,
Recently I was puzzled because some code in a package under development,
which consisted almost entirely of a .Call() to a function written in

R_CheckUserInterrupt() can be a performance bottleneck within GUIs
It seems benign, but has implications since checking time is actually not a cheap operation: adding jus ta time check alone incurs a penalty of ca. 700% compared with the time it takes to call R_CheckUserInterrupt(). Generally, it makes no sense to check interrupts at every iteration - you'll find code like if (++i % 10000 == 0) R_CheckUserInterrupt(); in loops to make sure it's not called

Initial user password
Hi list.
I am new to the list, but not so new to samba. Though i have a question.
I am migrating to samba 3.0 and want to setup users using pdbedit (like Volker
Lendecke showed at the Linux Kongress in Saarbr?cken; very fine tutorial, thanks!).
Is there a way of setting an initial passwort like "test" and to force the user to change it
after or while the first login?
Perhaps it is a

R_CheckUserInterrupt() can be a performance bottleneck within GUIs
A more generic solution would be for R to throttle calls to
R_CheckUserInterrupt(), because it makes no sense to check 1000 times
per second if a user has interrupted, but it is difficult for the
caller to know when R_CheckUserInterrupt() has been last called, or do
it regularly without over-doing it.
Here is a simple patch: https://github.com/r-devel/r-svn/pull/125

This seems like a great idea. Would it help to escalate this to a
post on R-bugzilla, so it is less likely to fall through the cracks?

linear programming in R | limits to what it can do, or my mistake?
Question for 'experts' in LP using R (using the lpSolve package, say) --
which does not apply to me for the sort of problem I describe below.
I've run any number of LP's using lpSolve in R, but all of them to date
have objective and constraint functions that both contain the same
variables. This lets you set up a LHS and RHS matrix/vector that are
symmetrical.
But, for a
