SAS has something called the "cubic criterion" cutoff for finding the most appropriate number of clusters. Does R have anything that would replicate that? I've been searching the lists and can't seem to find anything that would point me in the right direction. Thank in advance, Philip Bermingham

Hi All, is there any general advice about speeding up recursive functions (not mentioning 'don't use them')? Regards, Federico Calboli -- Federico C. F.

I have modified the parameters for a function (for my own use) in the stats package, but I assume I need to update the parameter set in another file as I'm getting the following error when I run R: The compile works fine so I assume there is a configuration file in the base package of R that needs modification. Error in parse(file, n, text, prompt) : syntax error on line 11102 Error:

I'm hoping someone can help me. I have downloaded the proj4R.zip and under my version of R (2.3.1) I install the package from local zip file. This worked great. I then type library(proj4R) to load the library and I get the error: Error in library(proj4R) : 'proj4R' is not a valid package -- installed < 2.0.0? I have read through the install documentation and have downloaded and

I'm trying to compile R on Windows 2003 Server and following the instruction laid out in R inst and admin manual I continue to get this error: make: ./Rpwd.exe: Command not found make[1]: ./Rpwd.exe: Command not found /cygdrive/d/rp/tools/bin/make --no-print-directory -C front-ends Rpwd /cygdrive/d/rp/tools/bin/make -C ../../include -f Makefile.win version make[3]: sh.exe: Command not

What is the best way to set up a project in visual studio, work on R and re compile? Is it better to use a different compiler or programming environment? I specifically want to work on C and Fortran extensions. Philip Bermingham [[alternative HTML version deleted]]

Hello, I''m a Java developer and I''m looking at Rails as a very interesting thing. I read the article http://theserverside.com/articles/article.tss?l=RailsHibernate and saw a couple of things that I didn''t like too much: 1) The N+1 problem This has been discussed in the thread (or should I say "flame"?) "Java people want to beat us". It seems

For those haven''t seen it yet, Patrick Peak has an interesting article at the Server Side (www.theserverside.com) discussing the differences between the Hibernate (www.hibernate.org) peristence framework and ActiveRecord.  The article can be found here: http://www.theserverside.com/articles/article.tss?l=RailsHibernate .  Patrick Peak is the author of _Hibernate Quickly_ (Manning), which

Hi, and sorry for asking such an unspecific question. Does anybody know of statistical / data mining methods that are available in R that are not in SAS ? With SAS I mean the SAS System Version 9.4 and SAS Enterprise Miner. I don't expect a complete list, just two or three examples or hints where and what to look for. I found some older comparisons, and the R methods mentioned there

I wonder if someone would confirm something I'm 99% sure of from the docs and discussion on the list, but can't find stated explicitly: R works only on problems that fit into (real or virtual) memory. Thus, even if you have a problem (e.g., simple regression) that could be solved by doing some operation on each row of a dataset at a time, you can't solve it unless the entire dataset

Hello! I have tried to build and install latest version of R, but I am not able to perform the install, due to seg. fault. I did the following after SVN checkout and wget for recommendeds: ./configure --prefix=/usr/local/R-devel make make install ... ... tcut text html latex example tobin text html latex example

Dear R-Helpers, SAS Institute just mailed out the notice below regarding a survey of people who do data mining. To help keep the survey from becoming biased toward commercial software, I thought it would be good to post it here as well. Cheers, Bob Fourth Annual Data Miner Survey Rexer Analytics has asked statistical and data mining software vendors to forward this survey as a courtesy. (SAS is

I have recently been reading several books on data mining which contain a few data sets.  The books offer some perspective on model choices, tuning decisions, result interpretation.  Are there any good resources that can walk me through the thought process of an experienced data miner with the datasets that are included for packages such as "rpart" & "kmeans". I

Hi all, I'm working on a multinomial (or "polytomous") logistic regression using R and have made great progress using multinom() from the nnet library. My response variable has three categories, and there are two different possible predictors. I'd like to use the likelihoods of certain models (ie, saturated, fitteds, and null) to calculate Nagelkerke R-squared values for

Hello R-users, I am interested to know if there is a tool that allows us to build SAS Enterprise Miner like workflows using the R scripts. For example, let's say I have the R scripts/functions for the following tasks: 1. Data Cleaning 2. Model Building 3. Model Validation 4. Visualization I would like to drag these functions into a workflow and run them together (output of one function

Hi: For those of you who are adept at both SAS and R, I have the following questions: a) What are some reasons / tasks for which you would use R over SAS and vice versa? b) What are some things for which R is a must have that SAS cannot fulfill the requirements? I am on the ramp up on both of them. The general feeling that I am getting by following this group is that R updates to the product are

Hello there, apologies for cross-posting my question is not an S/R question but there is so much knowledge concentrated in those lists that I thought someone could point me in the right direction. A few months ago I read an article in a referenced journal comparing some data mining programs, among which there was Insightful's I Miner, SAS' Entreprise Miner, SPSS' Clementine (I think)
