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

I request members of the R community to consider filling a short survey
regarding the use of R.
The survey can be found at http://goo.gl/jw1ig
Please accept my apologies for posting here for a non-technical reason.
The data collected will be suitably analyzed and I'll post a link to the

Image into Excel file from R
Hi useRs,
I would like to know what R users are employing to get their
images/plots created in R, into Excel sheets.
I am aware of the various packages (xlsReadWrite, RODBC) to get data
frames into R, but I would like to copy images too.
Thank you for any help in solving this problem.

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

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.

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.
Using the function acf(dtxts,plot= TRUE,xaxt = "n",col="red",na.action
= na.omit) (where dtxts is a time series object created with package
"xts" ) results in the error below.

Building GUI for custom R application
HI R users,
I would appreciate information/examples/suggestions on building GUIs
for R applications.
I am currently working on a project that would require the following
functionalities :

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.

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

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

In trying to take R to engineering undergraduate students, I have been
