I had the Salted Login Hash Generator working at one point and then it just stoped working. It was around the time that I changed hosts and I think that it just might not be able to connect to the new server. I have tried everything though and it just doesn''t seem to work out. I''m now thinking that maybe it has to do with something else that I changed in the project. Is

Dear Rubyists/Rails gurus, Though I''ve successfully completed the various Rails tutorials online and the Depot application from the Agile Web Development with Rails book, I''m still pretty much a Ruby/Rails newbie. I''m trying to learn by writing my own simple blogging application, but I''ve run into a problem that has had me scratching my head for a few days now.

This is it. We''re a mere two shakes of a lamb''s tail from releasing the final version of Rails 1.2. But before we light the fireworks and pop the champaign, we''ll just do one itsy, bitsy, tiny test run. Like wearing protection glasses in downtown Copenhagen on New Year''s. You know, just for precautions. So please do give it a good run. We''re looking

Hi, I have a file fileFoo.R, say that contains these two lines, invoking function foo that is specified in "foo_details.R": source("foo_details.R") foo(parameter1) I want to specify and pass parameter1 in my command line when invoking R in linux: R --no-save <fileFoo.R. How can I do that? And how can I retrieve the value of parameter1 in my fileFoo.R function

Hello, I have a dataframe with columns like: parameter1 parameter2 metricname value and I'd like to transform it into a dataframe with columns: parameter1 parameter2 metric1 metric2 metric3 where the values for each metric would be in the appropriate column. There are often multiple values for a given (parameter1, parameter2, metricname) triple. In this case, I want to use the

I have a list x (say) that will contain many inputs to and outputs a model. x$input1 <- assign.input1(parameter1, parameter2) is one way to assign input1, but it would be neater to be able to do assign.input1(x, parameter1, parameter2) Is this a good idea? If so, what is a good way to do it? -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing

Hello, I'm new to R but wan't to use it to compute the statistics of my medical study. The study includes several parameters for a number of patients. Each parameter was assessed by a number of readers, once with a special condition, once without. Now I have a data.frame with colums like: PatientID, ReaderID, SpecialCond(yes/no), Parameter1, Parameter2..... the rows are not sorted, and

Hello again list, I thought I'd start a new thread, seeing as it's completely different from my previous question. Some functions I have written require many parameters, and so do not fit nicely into an 80 column width display. This is usually avoided, by spreading that particular statement over a few lines. This is something that I do in Matlab with the following: myFunc(

My question is how have people implemented different types of users in their Web applications using user-engine? As for my application, I use single table inheritance in order to derive several different types of users, such as "moderators," "editors," etc ... For example, let''s say that I want to create a moderator. I define a new moderator class and Controller like

Dear puppetteers, I am having a philosophical question about parametrized classes. When building modules, one wants to be as flexible as possible, to try to target as many puppet flavors as possible. This is our target: - Foreman users, using foreman as an ENC with smart variables (or potentially any other ENC, but I would say this is the most widespread one). - Pure Puppet''s site.pp

Hi there: I'm trying to run a large number of nonlinear regressions on a time series dataset, where the data will be formatted something to the effect of: ObservationID,time,dependentvar I'll have a number of time and dependentvars for each observation, and I want to apply a nonlinear regression to one ObservationID at a time, and I want to have a dataset that is the parameter

This seems like it must have been asked before - I really _did_ try to find it in the archives, so my apologies if it''s already out there. Utilizing ActiveRecord, I would like to specify a prefix for the column names in my table. For example, in ''Recipe 16 Integrating with Legacy Databases'' (Rails Recipes, from PragProg, by Fowler) they deal with integration with a
