Dear All: I create a file named :"P_Value" with only one simple function: P_Value <- function( Table ) { S = fisher.test(Table, alternative = "two.sided"); return(S$p.value); } However, it seems that it's impossible to use this function directly, because no matter where I save this file, R always reports

Hello, I have a question regarding the use of Mocha with rSpec to spec one of my methods. My spec contains the following vehical1 = mock() vehical2 = mock() vehical1.stubs(:mph).returns(150) vehical2.stubs(:mph).returns(250) comparer.add_vehical([@vehical1, @vehical2]) comparer.sort_by(:mph) The comparer is an object that has a basic "stack like" functionality, add_vehical is the

Hi all, with PowerPoint and ThinkCell one can draw something they call waterfall chart and it looks like this: http://www.think-cell.com/products/images/waterfall.gif I found discussions on waterfall charts in the archive of this mailinglist, but unfortunately they looked totally different. Other names for this type of plot seem to be bridge chart, cascade chart, stair case chart, etc. but

I have a script that I am using to populate a database from a CSV file: RAILS_ENV = ''development'' require File.dirname(__FILE__) + ''/../../config/environment'' require ''csv'' # Destroy existing data Residence.destroy_all # IMPORT DATA FROM apartments.csv db_file = "#{RAILS_ROOT}/db/apartments.csv" CSV.open(db_file, "r",

Sorry to trouble the list with another Dreamhost problem, but looking through the archives I see nothing that can solve my problem. I have installed my app as per http://wiki.dreamhost.com/index.php/Ruby_on_Rails#Quick_Start_Guide_August_2006 with a symbolic link from my_domain.tld in ~/ to ~/apps/residence/public/ I get the Rails welcome screen. I have uploaded my app directory etc, and

Does anybody have experience with running ferret on dreamhost ? My app is running ok until I install the acts_as_ferret plugin, at which point I get "Rails application failed to start properly" errors. I''ve used script/console to confirm that I can require ''ferret'' and make a new Index object . Everything appears to be ok in that respect. Unfortunately

Hi, Is there an easy way of converting a gem to a plugin, or at least something you can dump into $RAILS_ROOT/vendor? I''m uncomfortable having stuff like capistrano, the shipping gem, builder, autotest being installed globally as a gem instead of being installed for each application. What do you think? Joe

I have set up a ferret search using the examples in the demo app. Is it possible to have the search terms included in the URL, so that, for example, users can bookmark a search results page ? Chris -- Posted via http://www.ruby-forum.com/.

I have the following action in my controller def search @query = params[:query] || '''' unless @query.blank? @results = Residence.find_by_contents @query end end In my View I have <div id="search-box"> <%= form_tag( { :action => ''search''}, :method => ''get'')%> <input type="text"

to another? i would like my website to be able to have the user to fill out a web form. i then would like to have a view of my own to either accept or reject what the user filled out. if i accept it, i want the info deleted from where it was stored and then store it to the ''public'' database. i guess its all of a matter of saving each field in the form to a temp table. when

Dear R-list members, I have a problem with translating a mathematica script into R. The whole script is at the end of the email (with initial values for easy reproduction) and can be pasted directly into R. The problematic part (which is included below of course) is <--- Original Mathematica ---> (* p_svbar *) UiA = Ni (Dsi - 2Di A + A^2)/2; UiiA = Nii (Dsii - 2Dii A + A^2)/2; psvbar =

Does anyone know of any RSpec screencasts for dummies, like me :) I have a Java background, but I have never written a java test in my life. I''ve never learned about TDD or BDD so I''m totally blank on everything that has anything to do with testing and stuff. Where should I start?!? ;) Christian... --~--~---------~--~----~------------~-------~--~----~ You received this

I''m currently trying to install the latest version of Ferret (0.10.9) on my Ubuntu Dapper (6.06) system. I have tried the gem, but it does not generate the ferret_ext.so file. Ideally I would prefer to install from the gem, but if source works, I''m fine with that too. I am now trying an install from source, but when I run the command ''$ rake ext'' I get the

I have been learning Rails and building small things over the last several months. Question I have that has been surprising difficult to figure out is this (I know it seems somewhat nonsensical but ignore that). I recently started getting a few requests for basic website to be built, small businesses, stores, even individual people. How would one about doing such a thing using Rails? I may not
