Dear R-users, I am having a problem with passing an argument to a function in a do.call function which itself is in a for statement. I am building a function to upload question pools to the blackboard learning environment. This function which transforms questions to XML style output should be generic and allow for any function to generate questions. Therefore I use do.call in this function.

Basically, I''m trying to have a table called "categories" have a many to many relationship with itself. But I also want each catagory to be able to be "copied" into another category so it is essentially a child category to more than one parent. To me the obvious way of doing this is by creating another table called category_maps (and a model called CategoryMap).

Can anyone supply me with a simple, succinct explanation of what the difference is between the "new" controller and the "create" controller that the scaffold generator produces? I run: > script/generate scaffold modelname controllername And now I need to do some work inside the controllername.rb file. For example, pulling a list from another database table to supply

Hi! Several people noticed problems with openssh Version 1.2.2 through 1.2.3 related to X11 forwarding under Linux.

Got a noob question for ya... When I visit http://localhost:3000/ I get the nice "Welcome to rails" page. To get to a controller I have to go to: http://localhost:3000/controllername What if I don''t want the welcome message and want / to resolve to a controller? How do I set that up?

Dear R users. In a loop, I set the title of my graph with : mytitle = expression(paste(delta^13,'C Station ', i) title(mytitle) However, instead of using value of i, it will literally use "i" character. Any one know the way to concatenate the value of i to the mathematical expression? With regards, Phil -- View this message in context:

Dear all, Maybe, I am doing something wrong, but using R-2.5.0 on my Intel-Mac, I have problems using function callNextMethod() in method initialize. I am loading the following code as file "testS4.R": setClass("baseClass", representation(myname = "character", mydir = "character", "VIRTUAL"),

Newbie here, I am trying to set up Routes so that it will look up a listing in my directory by sanitized phone number, like the following: www.domiain.com/5405551212 which will in turn list all the listings with that phone number (though they might be in the Db table with parenthesis and hyphens), if one listing, then make it a special render If anyone could help with my Routes code and my

I''m trying to render a component that pulls information based on a parameter that is passed by a link_to item, but my params object is nil for the following code in the controller: records = ControllerName.find(params[:id]) but the error page also has this: Parameters: {"id"=>"7"} I''ve tried to access it (in the controller) using: variable =

I''ve stucked to such problem: I have html entities in database, after using scaffold I''ve got these chars not converted (I have strictly " and & in page source). It is what I need, but after making ./script/generate scaffold modelname controllername (recreating controller) I''ve got all special chars converted into entities like (&quot and others). How can

Hi, Is there a way to turn off the automatic inclusion of "./" at the beginning of a path specified in an \SweaveInput{} instruction? I'd like to create some reusable "template modules" of Sweave code and put them in a standard directory like /Resources/Affymetrix Then the corresponding file that uses one of these would include a command like

When I started developing my application I grouped my controllers in the followin g fashion: User::ControllerName. Now I''ve realized that the ''User'' module is a misnomer for my current controllers and I need to use the User module for something else, so I decided to change the controllers in the ''User'' module to ''Data''.

Dear List, yes, me again trying to work with qplot ;-) I would like to make several single plots within a loop, like this (simplified and so on...): trials <- c("A","B","C") mycolours <- ("wheat","darkolivegreen","lightgreen",

No encuentro mi mensaje en la lista para continuar el hilo, encontré el problema, no lo comprendo del todo pero cambiando jpg por png funciona, aparentemente hay un inconveniente para guardar en jpg.

I''m using template components to modularize an application I''m working on and am really happy with the way it''s going. Unfortunately, all my attempts at writing functional tests for them fail. Trying to duplicate my normal controller tests I have: require File.dirname(__FILE__) + ''/../test_helper'' require File.dirname(__FILE__) +

Dear R-ers, I hope there is a really simple solution to my problem. I've written a function that I saved in an .r file. I source this file in my code. For a while it worked fine. But then when I run the line: source("F mylineplot.r") I started getting a warning: In readLines(file) : incomplete final line found on 'F mylineplot.r' I have no idea why - I tried to check and

I need to include another helper module apart from the normal two (ApplicationHelper and [controllername]Helper). The inclusion needs to be dynamic and based on external parameters (ie what helper that get included differ from request to request). Is it possible? How? /Marcus
