similar to: "Pursuit of Happiness" ? Are you sure ?

I''ve been deploying local applications into production (both linux boxes) with Switchtower, and I''ve had no problems, until now. I just tried doing a "rake deploy", and I get this error: ============ [update_code] exception while rolling back: NameError, uninitialized constant OSSL rake aborted! no such file to load -- openssl ============ Now, on both the production

All, I'm a newbie to R and I am interested in seeing a simple example of calling a 3rd party Visual Studio generated DLL from RStudio. Does anyone have a simple example which also walks through the preliminary steps of setting up the INCLUDE path and the library path to either a DLL or LIB file ? I have tried to find an easy example, but thus far had no luck finding an example using Rcpp

Hi R Gurus: I'm putting together an article about some R stuff in Latex. I refer to packages and functions. I think that I use {\em} for packages and {\tt} for functions. Is that correct, please? Thank you in advance! Sincerely, Edna Bell

Dear R-developers, I am trying to experiment with projection pursuit (PP), and different indexes for the same, especially using the tourr package. However, I've noticed that a PP index in the said package is only a function of the projected data. Could I modify the function so that the index sees the projection bases instead (or in addition to the data) ? Alternatively, if some other package

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

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

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

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 would like to have a login box setup so that if incorrect info is submitted, the box "shakes" via Effect.Shake. If the correct information is submitted, I want to redirect to some other page. The only solution I''ve found is the following, which is pretty ugly, as it displays the javascript I''m invoking on the page prior to the redirect. Here is the code: The Form

Hello ! I''m trying to implement something similar to the "multiple updates" section of the Web2.0 chapter of the Agile book. I implemented my version, and nothing is happening. No javascript errors, my logs look fine, page is rendered fine... just no Effect.Highlight. Here is the code: views/causes/cause_home/index.rhtml =============== <%= form_remote_tag(:complete =>

Hey All ! I have a form which contains two models. I would like both models to be validated, but have their validations aggregated on the page. If I do: <%= error_messages_for(:model1) %> <%= error_messages_for(:model2) %> It puts two big validation blocks on the page. I would like all the errors from both models, but only in one validation box. Is this possible ? All my attempts

I''ve implemented Ferret, using the instructions here: http://wiki.rubyonrails.com/rails/pages/HowToIntegrateFerretWithRails I get no errors in the application at all... however, I always get 0 results. I built an index off of some data, it exists in the index/ directory, the form submits find... etc... Just 0 results... all the time :) I confirmed the data from my models is being put

7 Jan 09 Hello, I am using R version 2.7.0 in a Windows XP context. I am also using the glmm.admb package (created by Dave Fournier, Hans Skaug, and Anders Nielson) to run mixed-effects negative binomial models. To the best of my knowledge and ability, I have searched and studied the R-help, R-sig-mixed models, and ADMB NBMM for R (through Otter Research Ltd) list servs; R help

Maaaaaaaaaaaaajor sanity check needed. I wrote a simple little plugin, and it wouldn''t load. I put some comments in it''s init.rb, and it didn''t even spit those out. So, I dug into the initializer.rb (/vendor/rails/railties/lib/initializer.rb) to see wtf is going on, and found the problem... but... can''t explain it. Here is the code in question:

Hello, I found my Rnw file generated strange symbols in pdf file. For instance, on page 4 of the following file, http://cran.r-project.org/web/packages/cts/vignettes/kf.pdf you can see Belcher et~al on line 2, and Figure~1 on line 5. The symbol ~ should not appear in the pdf file although the symbol was in the original Rnw file (something like Figure~\ref{...}, section~\ref{...}). On page 1,

Can anybody share some examples of their Money implementation ? I''m trying to setup a Model to use this library, but can''t seem to wrap my head around how it is exactly supposed to work. My Model (Foo) looks like: =============== composed_of :commission, :class_name => "Money", :mapping => [ %w(commission_cents cents), %w(commission_currency currency) ] Yet, in

In my daily development, I migrate back and forth between versions, and often do: rake load_fixtures... ... in order to populate my development database with fun data. Now, with any HABTM relationship, there are failures, as there is no way to say "which" fixtures to load first. Within an actual functional or unit test case, you could simply load them in the proper order, but
