similar to: grep or other complex string matching approach to capture necessary information...

Hi, I hope this isn't a really simple question, I've been struggling with it for a while. I'm looking for a way to get a function to go through a data frame line by line, compare fields, and produce a result, kind of a transform and an if statement combined (I tried to put them together and it didn't work). So, consider data Sales: House number Inspected Sold 1

Hello, I would like to have a function that retrieve matching strings in the same way as with java.util.regex (java 1.4.2). Example: f('^.*(xx?)\\.([0-9]*)$','abcxx.785') => c('xx','785') First of all: Is it possible to achiev this with grep(... perl=TRUE,value=TRUE )? As I would call this function very often with large data, I'm reluctant to use Sjava

I''m just getting back to looking at backgroundrb after a long hiatus since June. I''m looking at creating some workers but I''m a bit stuck as to how I should write tests for them. What''s the recommended approach for unit testing of workers? The project will ultimately be used by a Rails app but I''m comfortable developing the worker code as a

Hello, I''m working on a Rails app with a fairly complex set of model relationships. I''m abandoning my MySQL based search mechanism for Ferret/acts_as_ferret in the hopes of being able to more easily and effectivly enable searching. Before I get coding I was wondering if you folks might be able to tell me if my plan makes sense, or what could be a better way. The situation is as

Hi, Just wondering what the most popular approach is for authentication and authorisation in a rails application that is deployed and fronted by apache? Also when there are say a couple of rails apps being hosted. Authentication ============== [1] Options would seem to include: * Do it within rails/your app? Use of a "before_filter" per the Rails Recipes book * Use of Apache to

I wrote a rexml script that parses rather big xml files (DOM parsing) and builds an object out of them. This is what it looks like after i parse the xml file and display the object: [#<Article:0xb79e7428 @brand="This is a story from ", @id=5337, @fblurb="burb", @ntype="news type here", @copy="Copyright \302\251 2006 ", @source="source",

My app lets users fill in some forms and then creates an XML file from the data they enter. I''ve got the XML file saved on the server, and I''ve got the data they entered sitting in the database. Now I need to create an HTML file from that same data. What''s the Rails way? Is there an XSL transform function somewhere I could use on the XML file? Or should I go back

I doing an app to allow people to search bus time tables by bus stop and time. My models are: Providers -> Services -> Runs -> Stops <- Stations Key: "->" denotes a one to many Providers = Bus companies Services = the bus number Runs = Columns on a bus time table Stops = Cells on a bus time table, basically a time Stations = Rows on a bus time table StationA 10:00

Hmm...what about creating the block in the constructor? e = Event.new{ puts "Hello" } e.set(0) -> "Hello" e.close Well, I''ll try to hang out on IRC this weekend much of the time if anyone wants to join me to discuss this in more detail. Look for me in #ruby-lang or #win32 on freenode.irc.net Dan

Hi, I''ve been googling around looking for a good approach to doing live updates of my webpage. I''ve got a fairly extensive application already, using traditional rails, and I''d like to have a page update in real-time, hopefully without having to completely rewrite the app. One of the most promising approaches looks like Faye, but the railscast I saw was from 10 months

I'm about to add weights to a bus on-board survey dataset with ~150 variables and ~28,000 records. My intention is to weight (for each bus "run") by boarding stop and alighting stop. I've seen the Rake function of the Survey package, but it seems that converting to a "svydesign" might be excessive for my purpose. My dataset has a huge number of unique

Dear r-users, Any such a way that we can compute SPI using kernel function (nonparametric approach) without assuming any parametric distributions? Any existing package for above method using R? Thank you for your help. Fayyad [[alternative HTML version deleted]]

Hi, does anyone have experience with or could recommend: 1. The best approach to build an app for uploading and resizing a high volume of photos contributed by users. 2. An uploader to allow users to upload multiple photos at a time vs one at a time. 3. Best image processor. I''ve been told by a friend that Mini Magick performs best under high load, would be interested in any real world

Hi, I see there are multiple code coverage solution infras supported by LLVM. * LLVM native support code coverage (Source-based code coverage) * Gcc’s/gcov native code coverage support and * Sanitizer coverage All 3 of them are quite different. So, in terms of future support and technical aspects wise, would you please help me understand which one is preferred one? I am basically

Hi All, Producing release notes at the end of the release is a becoming more of a problem as the project grows. I've been doing this by going through all of the LLVM commits since the last release and pulling out things that I find interesting and potentially impactful to people. However, as the project grows and there are more commits, this has been becoming less and less practical. To

Dear all, I'm happy to share a recent publication on a bounded model checker for concurrent programs represented in LLVM IR that integrates the verification framework that I'm developing: Marcelo Sousa, and Alper Sen, LLVMVF: A Generic Approach for Verification of Multicore Software.

I did an install of Lotus Approach from the SmartSuite disk. v.9.8 and it works fine. I have not found any functions that don't work. I installed the Organize at the same time but that does not seem to want to start. I tried to make an account to post this to the application DB but I never have received a confirmation email so can't log in there as my account is not active. Tried to use

I had to reinstall my Mandriva distro a few days ago. The last install I had Wine and had no problem installing Lotus Approach via WINE. After the new fresh install it will not install. I can't provide any particular error as all I get is a window with ever increasing error numbers in the title bar but no information. I have to force quit WINE at that point. Why would it work fine once
