Hi, Day 3 with rails here. Forgive me. If this has been covered many times before, pls just point me at the article. I worked through the Rolling with Rails tutorial (http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html) built up my cookbook. Things work great. I now want to add Ingredients to my app. So, a Recipe will have 1 or more Ingredients and any single ingredient can be

I''m new to RoR and trying to make a HABTM relationship work. I have no problems with displaying the fields (after I pumped the data into MySQL manually outside of RoR), but when I try to edit a record, it =does= save the changes in the primary record, but =not= the join table. When I look in the development log, I see the update to the main table, but nothing about the join

Hi all, I''ve got an odd issue. I''m new to Ruby/Rails and have a bit of a silly question. I''m following along with the nice little tutorial here, to get an idea of the system: http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html?page=3 However, I''m running into an issue where the author adds a new field in his database, refreshes the browser and shows

I've downloaded and built LLVM 2.2, and I'm now trying to get to the point where I can get through the first tutorial (which seems to assume that you're already to the point of writing code and linking against LLVM). I've found the Projects.html doc page [1], which describes how to set up a project in the LLVM way. But some things are still unclear to me. (Please

Greetings! I''m new to Ajax and am trying to get a basic app working as a vehicle for learning it. The app is an extension of the cookbook tutorial. My intent is to be able to add a list of ingredients for a recipe. The page to add ingredients uses Ajax. As ingredients are added to the page they''re displayed in a "green-bar" format like that used in the Depot

The LLVM Tutorial, https://llvm.org/docs/tutorial/LangImpl01.html provides an excellent introduction to language definition and code generation. I am looking for a similar example that demonstrates how to use SmallString. Even a small test program, ———— #include <llvm/ADT/SmallString.h> int main(int argc, char **argv) { llvm::SmallString<32> str("hello world\n");

Hi all, Having successfully gone through Bill Walton''s Tutorial ''Rollining with Ruby on [Instant] Rails'' I decided to tackle John McCreesh''s ''Four Days on Rails'' Tutorial. I changed the Rails version as recommended in the tutorial. All went well until I entered the following command:- ruby script/generate model category I got:-

Hi, Coming to R from SAS... I have a data.frame A with 2 long factors "x" and "y". I want to get a count of the number of rows with each level of "x" and "y" jointly. 'table' seemed like it would work, but as I have many levels, the matrix output is pretty useless to me (and I don't care about zero values). How can I get output that looks

1. I'm running - or trying to run - BackupPC under Centos-5.2, and have been looking at various BackupPC HOWTOs and tutorials. I see that the "Falko" tutorial at <http://www.howtoforge.com/linux_backuppc> recommends (on page 3) that one should enter one's username, "falko" in this case, as the user in /etc/BackupPC/hosts . Other tutorials suggest one should use

I am just about working through Faraways excellent tutorial "practical regression and ANOVA using R" on page 24 he makes the x matrix: x <- cbind(1,gala[,-c(1,2)]) how can I understand this gala[,-c(1,2)])...

Hi, I use Mandrake 10.1 . I'm new with wine and I have many questions maybe not really clear because I try to understand. I tried many wines versions. First I tried the latest wine but no config with it. I tried given config or winetools. But winetools asks me gettext.sh like in debian (but I am not debian). So I try to use gettext.sh for this debian but still doesn't work, don't

I''m not sure if this is the right place to ask such questions. If not, my apologies and please direct me where such questions are handled. I am new to RoR and have been following the tutorial in Agile Web Developement with Rails. I have successfully gotten RoR up and running on my Mac (OS X 10.4.6) and created a MySQL database. However, on page 57 of the tutorial, the command

I''m trying to get a Rico LiveGrid working, and I am a bit stuck on how to accomplish this. I have a page that successfully queries a controller and updates a <div> containing a table. I have two versions of the action; one uses the render_partial to return a rendered version of that table, and the other returns an XML-RPC document, and this is where I hit a snag. The Rico LiveGrid

Following the beginning tutorial, I typed help.start() and was given a choice of browsers. I picked chrome but got back that chrome is not found. I cannot seem to change or get rid of it now. I looked at /etc/R/Renviron but don't see anywhere to set browser (R_BROWSER = ${R_BROWSER ...etc) - nothing about chrome. I tried starting as "R_BROWSER= R" - same thing. How do I change the

Hey folks, sorry for the incredibly basic question but I'm stuck in the tutorial with link errors. I'm getting them both on cygwin (gcc 3.4.4) and linux (gcc 4.1.3). If I enter the tutorial pretty much verbatim, it compiles fine, but I get tons of link errors if I attempt to link with arguments provided by running llvm-config with 'core'. If I run llvm-config with 'all'

Howdy All, I am looking for some good tutorials (books, websites, whatever) for calculating/testing for Spatial Autocorrelation using R. Specifically, I am wanting to test for autocorrelation of a number of variables measured at a set of discrete locations. Up to this point I have been exploring the "spdep" package and I can get "moran.test" to work, but I am concerned that
