I''m trying to get some answers as to why I (my company actually) would go with RoR over TurboGears. The developer staff is fluent in both Ruby and Python so that is not an issue. Rails is well into its release cycle whereas Turbogears won''t be at 1.0 until later this week. They both do essentially the same thing and they both have cool features unique to themselves

Does anyone know if there exists a Task Scheduler module in Ruby on Rails like in TurboGears below? http://www.turbogears.org/preview/docs/scheduler.html I''m using Ruby on Rails for a multiplayer online game and I want to set checks at regular intervals to see if users are still logged in etc. Thanks in advance -- Posted via http://www.ruby-forum.com/.

Hi, I got this working. i had to get rid of an underscore in one of my variable names to work on RWeb. Thanks for your help though!! Natalie __________________ I think you have to be either honest or careful, since the code you submitted to Rweb is different with your former code! Why the condition was changed from "test<-subset(X, GRADE == 7 & Y_Q10A < 9)" to

Hello my friends Today at FISL (International Forum of Free Software), I''ve had the opportunity to watch a Turbogears presentation. The framework, itself is really weak in comparison to rails, but... When the guy who was making the presentation show the NEW 0.9 TurboGears Toolbox I''ve though: - Isn''t something like that in Rails? Well, after a little googleing

Lately, I see a dependency problem with R-3.2 systems. install.packages allows dependencies, but they are not installed so the install fails. I see this a lot with students who are able to install packages like ggplot2 but then can't load it because a dependency "stringi" is missing. Those students are generally using Windows, but today I reproduced the same on RedHat Linux with

Greetings, I am working on creating an interactive website that will generate R-code for users based in the information they input on the site. Currently, the R-code can be generated and downloaded to be run locally on a computer with R. However, I have noticed a number of applications out there that instead submit the code directly to an R-web server. Some examples seem to be:

I cannot discover how to set or find the working directory in Rweb, so that I can source() a file from the server. The file I source() must refer to a data file in its directory. setwd() does not do anything, and getwd() says that the working directory is in /var/www/cgi-bin/ (on Linux). (I have a student who installed R on her own computer and analyzed half of her data, and then her computer

I set up a local repo for testing packages. My packages are not showing up from the repository when viewed by Linux clients. I suspect this is a web administrator/firewall issue, but it could be I created the repo wrongly. I am supposed to run write_PACKAGES separately in each R-version folder. Right? Maybe other novices can use these scripts, if they are not wrong :) Here's the file

Hi, I'd like to execute simple commands and functions in R through a website, is there any service like this somewhere? I only found http://www.osvisions.com/r-online/ but it does not work (last update 2003) and the links to releated websites only give errors (if I calculate 7+3). Thanks for help & hints, Thomas

I'm looking for an optimal approach to access Oracle databases via RWeb applications. I'm new to R but familiar with programming functions and web pages for the S+ Statserver. I'm now going through the motions of migrating S+/Statserver applications to R/RWeb as a feasability exercise. I can access databases using ODBC directly in R or S, and using Statserver, but I have not succeeded

I ported Jeff Banfield's Rweb (http://www.math.montana.edu/Rweb/) to Windows. In the process, I dropped some things (non-JavaScript version, Rweb modules and data sets), but also simplified the installation process by removing the dependency on NetPBM. A Ghostscript dependency remains, however. See http://www.liquidmarkets.com/m.php?m=News&file=article&sid=6 for up-to-date

We here at HGSI have a consultant doing some statistical work for us. HGSI bought and installed SAS, but our consultant insists that R and Rweb is a better solution. I do not know either package so I do not know, hence we are ditching SAS for R and Rweb. Any comments on this are welcom. Now for the real problem. Rweb is very expensive (time wise). The number of prereqs is way more than I thought

Hi, How are you? I have a quick question.... I have code that works perfectly with R desktop, but does not work with RWeb. Could you please tell me how to modify the code below so it will work with RWeb? #Read in txt file happyguys<-read.table("c:/test8.txt", header=TRUE, row.names=1) #Subset the txt file to only include certain values test<-subset(happyguys, GRADE == 7

Hello list: I have some R code/data sets that i'd like to make available to others through RWeb server use.  The code/data were saved via "save.image" and should be made available by the following command sequence: con <- url("https:// ....") load(con) close(con) However, this is where the problem starts... For one thing, i am using google docs to host the R object

Hello, I have a setup similar to Rweb ( http://www.math.montana.edu/Rweb/ ): I get R scripts from users and need to execute them in in a safe manner (they are executed automatically, without human inspection). I would like to limit the user's script to reading from STDIN and writing to STDOUT/ERR. Specifically, preventing any kind of interaction with the underlying operating system (files,

I am trying to develop an interactive software and would like to know how I can hook up R to the web. Thanks Joe Warfield
