Hi, I have a spec it "should have a unique username " I have a code: validates_uniqueness_of :user_name Now, I don''t know how to test this code. In order to test this, do I need to run `save`? For example, @user = User.create(:username => "mike") @another = User.create(:username => "mike") @another.save.should be_false This messes up test

Hello, can anyone tell me if R has any special function for simulating the structure of human populations? Something like the genetic algorithm? I need to simulate a sample of a population with a specific structure. Is there something on R that can help me? Thanks to everyone. __________________________________________________________

Dear all, I have several questions regarding fisher.test() in R, and I'd highly appreciate any help with it. I have a group of observations, each having people's income, and an indicator of whether selected in or out a program. I want to test the difference between income of people who are in and out. Because the distribution is far from normal, I decide to use the fisher's exact

Hi, I wonder if anyone has written any code to implement the suggestions of Smart et al (2004) in the Bulletin of the Ecological Society of America for a new way of graphically presenting the results of logistic regression (see www.esapubs.org/bulletin/backissues/085-3/bulletinjuly2004_2column.htm#t ools1 for the full text)? I couldn't find anything relating to this sort of graphical

I've sometimes thought it would be useful to have another mail list called "no I haven't read the documentation but someone can save me a lot of time," or perhaps just "newbie" for short. This can be very useful for people just getting started in R and with school starting soon I expect the help list may become overwhelmed. Of course, I think that people should read all
