similar to: association rules in R

Hi all, is there a more convenient way to debug R code than the built in debug() function? (so that one can set breakpoints, step in and out of function calls,...). I read the section on debugging compiled code in the manual "Writing R Extensions" (I only want to debug ordinary code but thought that maybe the advice there could help), but didn't find out how I can start

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, ------------------------------------------------------------------- Rajarshi Guha <rxg218 at psu.edu> <http://jijo.cjb.net> GPG Fingerprint: 0CCA 8EE2 2EEB 25E2 AB04

Dear R-users! I would like to search for "association rules" (and compute support and confidence, for example) in a data set, and wonder if this can be done with R (version 1.5.0 for Windows)? Particulary, I wonder if a) anyone has done something like that with R or b)maybe someone has written an R-interface to some existing algorithm/software (e.g. to something like the

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

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

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

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

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

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).

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

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

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

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: At first the example, that works fine:

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.
