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

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

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.

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

time series contains internal NAs error
Hello R List, I seem to have a peculiar problem. When using time series data, I get the following error when running the acf and pacf function.

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

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
