Dear R-programmers, I am trying to program a Newton-Raphson in R (yes, i will try GSL, not right now), and it would be a real boon if R had tail call elimination, so that a recursive program has a guarantee not to fail due to stack overflows, given how slow loops in R are. I did look at the documentation, but could not find a reason for it. Regards, Mohit Dayal Researcher Applied Statistics

Dear R-programmers, I am trying out certain methods in R, and the statistics require me to calculate n-(sample size) dimensional equations. They are not really very hard to solve - my home-brew implentation of Newton-Raphson in R succeeds most of time with simulated data. (Note that I am assured of a unique solution by theory). Problem comes in with real data, for which I should really implement

Dear R-programmers, I would like to use one of the AS Algorithms that used to be published in the journal Applied Statistics of the Royal Statistical Society (Series C). FORTRAN code based on these are available on the Statlib website at http://lib.stat.cmu.edu/modules.php?op=modload&name=PostWrap&file=index&page=apstat/ with the disclaimer, *"The Royal Statistical Society

Dear helpers Does R have a package that performs projection pursuit density estimation? Or anyone knows code in Matlab or C for example to do this? Thank you all Luis

Hello, Just a quick question about ppr in library modreg. I have looked at Ripley and Venables 2002 and it says that projection pursuit works "by projecting X in M carefully chosen directions" I want to know how it choses the directions? I presume it moves around the high-dimensional space of unit vectors finding ones that separate the response variables, but how. I looked at the

Dear R users, I am looking for the source code of the implementation of ppr (Projection Pursuit Regression) in R. It will be great if citations of the source papers on which the implementation is based, are also provided. Thank you, Arvind Iyer, Grad student, Deptt. of Biomedical Engineering Viterbi School of Engineering University of Southern California, Los Angeles [[alternative HTML

Hi, Recently, I installed the 1.1.0 version of R (for Windows), since it includes an implementation of Projection Pursuit (I failed to write my own version of PP as a standalone C++ program). As far as I know, R offers two interfaces/sintax for the ppr() function. The first one requieres a regression formula and a data frame. The other requieres X, a matrix with the explanatory variables, and Y,

I've been finding that the "loose ends" in many of these older codes cause more trouble than it is worth in their use. When I encounter them, I've attempted to re-program the algorithm in R. A lot of the Fortran code is because of the software structure the author used and nothing to do with the job to be done. If you can prepare an R function for this, you'd be doing the R

Hi I am currently using facebooker to do some facebook connect. I found out that these functions are currently missing from facebooker connect.registerUsers connect.unregisterUsers I have modified user.rb and parser.rb to get these function going. I have verified that it works and would love to contribute stuff back. However I can''t figure out how to go about it. Any help would be

Hi, I am solving a projection pursuit regression problem, of the form y = \sum_i f_i (a_i^T x), where a_i are unknown directions, while f_i are unknown univariate link functions. The following is known about each f_i: 1. f_i (0) = 0  (that is, each f_i passes through the origin) 2. f_i is monotonic. Is there a way to ensure that the function ppr() in R produces solutions that respect the

Hello, I am using projection pursuit regression parameters selection. Does anyone has experience on the range to test for df parameter (spline kernel) and gcvpen (gcvspline kernel)? I don't find any information about this. Thanks in advance. Joao Moreira [[alternative HTML version deleted]]

Folks, The projection pursuit regression function in the base R seems to crash when the optimization level is set to zero, i.e. the initial ridge terms are accepted without refitting. I encountered this problem in an out-of-sample prediction exercise using predict. But further investigation suggests the issue is with the ppr fit and predict just sppeds up the crash. The other optlevels seem to be

Hi I am trying to use facebooker with an existing website that already has a model named ''User''. I therefore created a model called BkUser for use with facebooker. Also I have different controllers for all facebook requests. I am using acts_as_authenticated for handling login etc for my website and everytime a user is logged into my facebook app and tries to also browse the

I always kind of liked this title (the title of Davids super Rails presentation), but then I saw this quote today: "The pursuit of happiness is a most ridiculous phrase; if you pursue happiness you''ll never find it." by C.P Snow I''d have to agree with this quote. It''s the same as love... go looking for it, and you''ll never find it. Soooo... David,

Has anyone had stability issues with IAX2.

Asterisk logs show the phone being answered and various files being Played back. But

Adding Mohit who is experimenting with cgroups has found some way to restrict glustershd's CPU usage using cgroups. Mohit maybe you want to share the steps we need to follow to apply cgroups only to glustershd. Thanks.

Hi Guys, I am trying to paginate the results from a search. When I use actual constants in the search conditions, it works fine: def query @k2_result_pages, @k2_results = paginate (:k2_results, :conditions => [''e_date >= ? AND e_date <= ?'', ''2006-07-12'', ''2006-08-12''],

Hi! I''m looking for a good tutorial that explains the main points of performing queries with Rails. I do have AWDWR and have read the section on ''find'' but I''m looking for something that goes into more detail on how to perform queries across tables. Abstracted from my current application, this is an example: * person has_many sites * site has_one room *
