Hi all, I am facing problem in getting subdomain name inside the model. The following is my setup. I am using cancan for authorization.I wanted a specific condition in Ability.rb ( the file which is placed in models if we install cancan gem). Below is the condition I wanted: ========================================================= user ||= User.new # guest user (not logged in) if

assume dependent variable y( continuous),independent variable x ( continuous),I try to categorize x with some interval,such that,those intervals would has most significant different effect on y. any one knows which method I should apply,I really need some hints,thanks so much~ [[alternative HTML version deleted]]

Hi the list, I am defining S4 objet. Is it possbile to define a method that change the slot of an object without using <- ? My object contain a numeric and a matrix. At some point, I would like to impute the missing value in the matrix. So I would like to use something like : ----------------- setClass("MyObj",representation(time="numeric",traj="matrix")) a

Hello. I have a UsersController and a Model called User with a "new" method, like this: class User < ActiveRecord::Base def test return 1 #I can do anything and return any data, the problem continues. end end The problem is that I cannot access my "test" function from the controller. It says that the method doesn''t exists. class

Dear All; I have used fbmSim to simulate a fbm sequence, however, when I tried to estimate the Hurst effect, none of the nine procedures gave me an answer close enough to the real value, which is 0.5 (n=1000). So, would you please advice, 1. which is the best method to estimate the H among the 9 mehods, R/S, higuchi or Whittle? 2. how to choose the levels (default=50), minnpts, cutoff values or if there is any other issues to consider? Would you please send your code if you can get the right estimate for the attached dataset? 3. I also simulated multiple sequences, but some of the estimated res...

Hello R Power Users, There is a rather large introduction you may skip to go directly to my question about S4 classes. I am working on some toy code to help me get in through S4 classes. Doing this homework, I have some questions about S4 classes. I have carefully read available help and some additional material such as Robert Gentleman's slides and special attention to "Programming

So....let''s have a look if I understood the issue: -Find_all_by is actually the same like Find(:all), however Find_all_by is much shorter and less complicated than the syntax of Find(:all) -So in my CONTROLLER it says @files = find(:all) however I don''t want to see all files displayed in my selection box, because I only want to see the foles whose mandant_id is the same like

Hi Railers, Is there a way to specify all relations in a :include option while find()ing? I have a model with a lot of associations, and sometimes i would like to query for all them. Something like Model.find(params[:id], :include => :all) would be nice. Alternatively, i don''t know if there is a mehod to retrieve all model''s associations, to do something like

...the newer version of the MachineCodeEmitter being submitted, when it is replaced by the ObjectCodeEmitter. Anyway I have attached the code for you to look at. It is also a endian speedup patch for included. The ObjectCodeEmitter patch should hopefully go in this weekend. There are inline raw*emit mehods, these and the reserveBytes method are intended on being used by the cpu *CodeEmitters so they just reserve the maximum instruction length and then use the raw methods to do writing. These and the endian speedup should help to make the raw mechanics of JIT code generation a bit faster. Aaron 20...

dear readers---I struggled with how to do nice fixed-effects regressions in large economic samples for a while. Eventually, I realized that nlme is not really what I needed (too complex), and all I really wanted is the plm package. so, I thought I would share a quick example. ################ sample code to show fixed-effects models? in R # create a sample panel data set with firms and years

Maybe behavior of 'as.list' in R is not inherited from S? - From https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=78 , in "the prototype" (S), 'as.list' on a data frame gave a list, not a data frame as given by the default 'as.list' in R. That led to introduction of 'as.list.data.frame'. - From
