I have table "decks" with three fields: "id", "created_at" and "cards" which is a 264-character string field. I have modified the model with a constructor, as follows: class Deck < ActiveRecord::Base attr_reader :cards def initialize @cards = "12345" end end If I call Deck.new from my controller, I get no errors and an object with the

Hey all, I'm relatively new to the R-environment. I'm having a bit of trouble with encapsulation. I have a globally declared variable that doesn't update it when I change it in a function. For example when I run the following function >deckn<-NULL >deck1<-1 #52 card deck >deck<-function() { #Creating a standard deck deck1<-c(1:52) deckn<-deck1 #Creating n

Dear List Members I used to play around with R to answer the following question by simulation (I am aware there is an easy explicit solution, but this is intended to serve as instructional example). Suppose you have a poker game with 6 players and a deck of 52 cards. Compute the empirical frequencies of having a single-suit hand. The way I want the result structured is a boolean nosimulation

Hi there, I''ve got installed ajax_scaffold_generator (3.1.2, 2.2.1) Anyway I''m following the example here <http://height1percent.com/ articles/2006/04/18/ajaxscaffold-3-1-0-released> which suggests the following in a model file: -------------------------------------------------------- require ''ajax_scaffold'' class Pet < ActiveRecord::Base

I'm doing a study where people place a deck of cards in a certain order. It's sufficient to assume that their colors & each has a number (it's actually about attributes of hobbies). I'd like to look for patterns in how they've arranged the deck. For each subject I have a list like 3,5,2,4,1, indicating that (s)he chose 3 first, then 5, then 2. . . . I think what I first

Hi all, just joined and have only just kicked off with Rails (coming, but not departing, from WebObjects development). And so far there seems to be a lot of promise except for one thing I can''t figure out as yet -- the above problem. Say I have the following conceptual relationships: ITEMS <<--->> CARTS i.e., each item can belong to one or more categories. So really

I have the following models: class Card < ActiveRecord::Base belongs_to :deck belongs_to :front, :polymorphic => true belongs_to :back, :polymorphic => true end class TextContent < ActiveRecord::Base has_one :card, :as => :front has_one :card, :as => :back end The conflicting has_one declarations don''t work. What I need is

Hi devs :-) At the Mozilla Festival in London recently, I took part in a Hack the DJ workshop, looking at ways to take digital DJ'ing to the next level: http://www.bbc.co.uk/blogs/researchanddevelopment/2011/11/setting-a-dj-challenge-at-the.shtml One of the ideas proposed was stem mixing, using multichannel files in DJ applications. A proprietary implementation of this idea is Fireplayer

Hi all, I'm looking for a contributed package that can provide a detailed account of missing data patterns and perhaps also provide imputation procedures, such as mean imputation or hot deck imputation and the like. Is there anything out there? Thanks in advance, David -- =========================================================================== David Kaplan, Ph.D. Professor

Hi I found on google that there is an implementation of hot-deck imputation in SAS: http://ideas.repec.org/c/boc/bocode/s366901.html Is there anything similar in R? Many Thanks Eleni Rapsomaniki

Hello. Using the ":include", which generates a "LEFT OUTER JOIN" SQL command, it is possible to eagerly preload second order data objects (children) for a given association. I wanted to know, if it is possible to eagerly preload and cache third order (or more) data objects, which are little-children or little-little-children. As I''ve seen. it is possible to add

Hi, I wrote a simple master function, run(), that has inside six qplot functions. The goal is to type run() and have all six graphs appear as separate windows so that I can copy them into PowerPoint for a client. When I type run(), only the last graph appears, the first five apparently being overwritten. How do I get all six in separate windows, ready for copying? By the way, is the a way

The linking state of a Debug build seems to require a humongous amount of memory. My poor little linux machine with 16G of ram swaps its brains out. Waiting for it to finish (if it ever does) is like the old days when you submitted your deck of cards and waited until the next day to see the results. To debug a new backend, is there a way to just get the debug info for the Target/Foo

Hallo list, I am running a samba server on Arch Linux. From time to time I get this error message in the system log (journalctrl, log from systemd). I have read the Trouble-Shooting section of the Samba HOWTO as pointed out in the error, but I could not find anything related. Can s.o. please tell me how to approach this error, or even tell me that the reason could be. Any help is really

I have my tape deck connected to my PC's line-in port, but Audacity's unstable release is unable to pick up the audio, though when I select the proper device and play with the volume control in the app, the audio does change. What other mp3 capture programs do people use? My goal is to simply capture each side of a tape to mp3, then use Audacity to break each song to its own mp3

Hello, I am getting requests to place our PDF slides (output from beamer) into Microsoft Powerpoint formats (.ppt). What's the best practice or any recommended software packages (any success with open or commercial) that we can use to convert PDF slides into an EDITABLE powerpoint deck? Thanks in advance.

Anyone here using Level 3 or AT&T wholesale sip terminations services? I would like to know on any minimums they would require? Also, an idea of how competitive the rates are. I am not asking to disclose your custom rate deck, just a "what to expect". Finally, if you guys can PM me contact info to someone from the wholesale department, I would really appreciate it. Kind Regards,

I'm using the survey api. I am taking 1000 samples of size of 100 and replacing 20 of those values with missing values. Im trying to use sequential hot deck imputation, and thus I am trying to figure out how to replace missing values with the value before it. Other things I have to keep in mind is if there are two missing values side by side, how do I replace both those values with the value

Hello, I have what I suspect might be an easy problem but I am new to R and stumped. I have a data set that looks something like this b<-c(2,3,4,5,6,7,8,9) x<-c(2,3,4,5,6,7,8,9) y<-c(9,8,7,6,5,4,3,2) z<-c(9,8,7,6,1,2,3,4) data<-cbind(x,y,z) row.names(data)<-c('a','b','c','d','e','f','g','h') which gives: x y z
