I''m sure people have encountered this before, but I''ve been unsuccessful at finding anything about it. Basically, I got a rails app that uses postgres and tsearch2 for some full text indexing and I''d like to be performing unit tests. Now, there''s the whole deal of how to get the test database to load all the tsearch2 information properly. I tried to come up

Hello, I am planning to build a bigger Internet platform and actually evaluating Java EE and Rails. I have a lot of Java experience and I am quite new to Rails. After playing some weeks with Rails I am sure that it is a mature web framework and I really like the productivtity of Rails. One of the key advantages is that new developers will understand this platform much quicker than all the Java

I am developing an application in German. This means I have umlauts. When I was using rails version 0.13.1 there seemed to be no further configuration needed for umlauts to be shown correctly. Now I have upgraded to 0.14.2 and the umlauts are being displayed at ''?''s. I changed the encoding of the page and it is UTF-8. I have also tried the steps listed at

Hi, I have been using myisam tables in mysql with rails because my client will soon want fulltext searchable content, however when I migrated my development db from schema.rb all of the tables generated were innodb. I understand that I can override this, but also like the transactions and foreign keys of innodb. So 2 questions really: 1. are transactions in activerecord dependent on innodb or do

Dear All, I have a database of 200 observations named myD. In the dataframe there are a column named code (with codes varying from 1 to 77), a column named "prevalence" with some quantitative measurements are given and an column named Pr_mean, with no values. I would like to set a cycle to compute the average of prevalence values for each different code and store the averages under the

I''m trying to figure out how to determine the width and height of images that are uploaded through my app. Either from the posted data or the file I save to disk. I''ve been searching around for info but no luck; I''m completely at a loss. Any suggestions or pointers would be great. Project background: The site is an artists portfolio site. The images are thumbnails

Hello Everyone, I was analysing big survey data using survey packages on RStudio. Survey package allows survey data analysis with the design effect.The survey package included functions for all other statistical analysis except two-proportion z tests. I was trying to calculate the difference in prevalence of Diabetes and Prediabetes between the year 2011 and 2017 (with 95%CI). I was able to

Dear Md Kamruzzaman, To answer your second question first, you could just use the svychisq() function. The difference-of-proportion test is equivalent to a chisquare test for the 2-by-2 table. You don't say how you computed the confidence intervals for the two separate proportions, but if you have their standard errors (and if not, you should be able to infer them from the confidence

Hey everyone, I'm working on a contour plot depicting asymptomatic prevalence at varying durations of infectiousness and force of infection. I've been able to work everything out except for this one - my legend title keeps getting cut off. Here's what I have: filled.contour(x=seq(2,30,length.out=nrow(asym_matrix)), y=seq(1,2,length.out=ncol(asym_matrix)), asym_matrix, color =

Hi, I am wondering if there is a way to specify the prevalence of events in logistic regression using lrm() from Design package? Linear Discriminant Analysis using lda() from MASS library has an argument "prior=" that we can use to specify the prevalent of events when the actual dataset being analyzed does not have a representative prevalence. How can we incorporate this information in

Hi, I currently have a site that lets people enter info and submit it to the database. But the problem is the it lets people enter data in their language (portuguese and spanish) and all the special characters for those languages get replaced by symbols. Any idea how would I fix that? Thanks a lot. -- Posted via http://www.ruby-forum.com/.

I''ve got a fairly basic problem here that I''m hoping there is an easy solution for. I have a chunk of html code that I want to truncate to a given length... say 20 characters or so. If I use the ''truncate'' helper function I end up with unbalanced tags. For example. <a href=www.someplace.com>A really long string of words</a> becomes <a

Hello, I'm an MD working in an eye clinic. I'm learning by myself to use R for use in my research works and for implementation in a software project.

I am working with the Government of Fukuoka, Japan to get the word out about the Fukuoka Ruby Award to Ruby developers in the US. It is free to apply for this award. The top prize is about $10,000. Deadline is December 25, so there is not much time, but the application is fairly simple for developers who have existing projects. Here are the details: Fukuoka Ruby Award

Dear R colleagues, consider my data.frame named "df" with 3 columns - being level, prevalence and sensitivity - and 7 rows of data (see dump below). df <- structure(list(level = structure(1:7, .Label = c("0", "1", "10", "100", "1010", "11", "110"), class = "factor"), prevalence = structure(c(4L, 2L, 3L,

Dear all, I have been stuck on this problem, am rather struggling and would appreciate some advice if anyone can help. I apologise if this is a bit long-winded, but I've tried to limit it to the bare essentials, but don't know how to make it more generic! I have some slightly odd real world data that I'm looking at representing number of positive diagnoses for different diseases,

I need to create a number of multi-step forms for creating models. Currently i''m looking at http://www.bigbold.com/snippets/posts/show/277 As a solution. Are there any other methods you guys would recommend? Are there any reusable (dry) methods of creating multiple multi-step forms? -------------- next part -------------- An HTML attachment was scrubbed... URL:
