RGtk2 help: Show list of column names from dataset and categorize as factor or numeric
Hi UseRs, I recently started working with the RGtk2 library. The documentation is comprehensive and I've tried learning from the examples in most Gtk tutorials (which have C code). This is a little problematic, but has helped quite a bit in getting me started. I would like to create a GUI for file selection, which then displays the column names from the selected file, and provides the user

Pre-model Variable Reduction
Hello All, I am trying to carry out variable reduction. I do not have information about the dependent variable, and have only the X variables as it were. In selecting variables I wish to keep, I have considered the following criteria. 1) Percentage of missing value in each column/variable 2) Variance of each variable, with a cut-off value. I recently came across Weka and found that there is an

R on Mobile Devices (Android)
Hell R-list, At the cost of sounding far-fetched and almost incredulous, I would like to know if any R user is remotely considering the use of R on Mobile devices, and Android in particular. I really do not have an idea of the kind of definite incentives in terms of using R on Android, but having an analytical engine on a mobile phone would allow for micro statistics to be collected from the log

Logistic Regression in R (SAS -like output)
Hello useRs, I have a problem at hand which I'd think is fairly common amongst groups were R is being adopted for Analytics in place of SAS. Users would like to obtain results for logistic regression in R that they have become accustomed to in SAS. Towards this end, I was able to propose the Design package in R which contains many functions to extract the various metrics that SAS reports.

Social networking around R

For this, I've set up a social network @ www.rstuff.socialgo.comand it would be great if you could post your comments on the forum created for this discussion. The News section has feeds from some of the R related blogs I've been following. I'm hoping for a central resource that keeps

Syslinux 1.75, LEAF Bering 1.2, Compaq 2266
I have been using the LEAF Bering firewall for a year or so. It boots with Syslinux 1.75. But Bering is too large for a 1440KB floppy, so it formats the diskette as 1680KB. Recently I found a small Compaq 2266 box to replace a larger Compaq 7170 to run the firewall. But when I try to boot the Bering diskette on the 2266 I get the following message: Loading Linux ............ Boot failed:

Ideal (possible) configuration for an exalted R system
Hi All, I am trying to assemble a system that will allow me to work with large datasets (45-50 million rows, 300-400 columns) possibly amounting to 10GB + in size. I am aware that R 64 bit implementations on Linux boxes are suitable for such an exercise but I am looking for configurations that R users out there may have used in creating a high-end R system. Due to a lot of apprehensions that SAS

URGENT: Shorewall Security Vulnerability
Javier Fernández-Sanguino Peña has discovered an exploitable vulnerability in the way that Shorewall handles temporary files and directories. The vulnerability can allow a non-root user to cause arbitrary files on the system to be overwritten. LEAF Bering and Bering uClibc users are generally not at risk due to the fact that LEAF boxes do not typically allow logins by non-root users. For 2.0

Learning development concepts in R for newbie users
Hi R users, I apologize for a seemingly trivial question, but I felt this forum would be the best place to seek advice. I have been an R user for a year now, but I am limited to using R and its various contributed packages. I strongly feel that users of a free and open source software tool must eventually provide development expertise. I am aware of the extensive documentation available on the

Dynamic visualisation of R data using Adobe FLEX
Hi useRs, I had posted about Adobe FLEX talking to R for rich visualisation. Reply from Jeffery Horner contained links to the revolution-computing.com webpage which had information pertaining to the Bay Users R group Meetup on Web Dashboards with R. I have a very specific project that I need to implement. I wish to use the graphics capabilities provided by Adobe FLEX to visualise outputs from R.
