S or R used in natural language processing (NLP)?
Dear All,
Does anyone use S or R for statistical natural language processing (NLP)?
All I have found so far is a package called EMU
(http://www.shlrc.mq.edu.au/emu/emu-splus.shtml) which is a speech
wave-form processing package.
What I'm looking for are routines to support text processing, text
categorization, word sense disambiguation, text understanding etc.
In particular, I would

How to beat Google aka Xapian & Natural Language Processing.
Xapians!
If tomorrow Xapian search engine would achieved the same performance
and result in searches as Google we would not be able to beat Google,
because we would create only a copy of the searches that already
exists from Google search engine. However there is a way to beat
anyone, and there is a way to beat Google successfully as well just do
not give up. Some see it as implementing Ajax, or

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.

R on Mobile Devices (All)
Hi,
I have been considering use of R on Windows Operating system and the market
leader Symbiosis.
I want to log on to my remote pc using remote desktop securely using the
username and password, then run R as if I was in front of the PC itself ( PC
got more RAM than Mobile ..still). Ditto for the Android and Ipod ( I mean
Iphone).
I then would like to mail the output using both Google Docs as

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.

R for Engineering (Mechanical, Industrial , Civil, etc.)
Hi useRs,
In trying to take R to engineering undergraduate students, I have been
looking for context that would make R more accessible to the said
audience. Though R is primarily a statistical tool, I would want to
demonstrate the use of R for certain engineering courses (Design of
Machine Elements - gear design, ball bearings, etc.) which would
generate interest in it and provide students a way

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

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

There is also the OptimizeR project on R-forge

I'll let their authors speak for themselves. Stefan Theussl did a good job in the Task

with all the work going on.

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

R as a web scraping tool using RCurl

I am trying to leverage my knowledge of R in trying to use it for tasks that
may not make R the best choice for these tasks.

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

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

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.

Does the R "statistical language includes modules/packages to carry out nonlinear optimization similar to the SAS NLIN and NLP procedures?
Hello R folks,
I'm hoping the answer to the question in the subject line.
I have in the past used SAS PROC NLIN and PROC NLP to carry out
nonlinear optimizations. I'm wondering if there is analogous ways for
doing this using R. If so, could someone please point me to some
literature that would help me examine this further?
Thanks very much.

Hi R users,
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
results in the coming weeks.

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 :
1) Display a window to the user. Provide a function to scan local
drive and choose dataset file.
2) Display the column names for the user to choose the dependent
variable and the independent variables.

Reducing code size of Position Independent Executables (PIE) by shrinking the size of dynamic relocations section
The generic-abi thread has gone into broader subjects of the benefits and
desireability of the work. I'm willing to take it as given that the
encoded size of pure-relative address relocs (i.e. R_*_RELATIVE
equivalents)--ultimately the RODATA segment size of a given ET_DYN file--as
sole metric is a worthy goal and the ballpark savings ratios we're seeing
are worth committing to a new ABI.
