Hello, I''ve come across an issue that I''m sure is a bug when using after_create with a has_one association, but I''m not 100% certain if I''m missing something. This is pretty much exactly the code I''m using. Two simple classes (Account and Contact) and I create the contact after I create an account (via after_create). I''m not passing in a

Dear R help list, I'm fitting a 'variable coefficient model' in the MGCV package and I want to plot the different smoothers I get for each factor level in one graph. So, I do something like this to fit the gam: Mtest <- gam(outcome ~ s(age, by=as.numeric(gender==0)) + s(age,by=as.numeric(gender==1))+factor(Gender)) Then I can plot the smoother for gender=0: plot(Mtest,select=1)

Hi, I am thinking about how to best design a quiz site in RoR. I think it should be fairly easy, but have run into a wall.

However, I can''t figure out how to "mark" the quiz. The form is submitted to the

Hi guys, hoping someone can give me a pointer with this? I have a Javascript variable that I''m updating dynamically as a user interacts with the page. I want the user to be able to save it''s value at any time along with some text data in a pop-up form, so the best way I can think of is to pass it through the params hash without writing it into the form.

We had used Samba alpha 17 (included in Resara Server 1.2) for a long time and has now migrate it to Samba 4.0.5 (Ubuntu + Zentyal 3.0 PPA) with NTVFS enabled .

I have installed the dovecot 1.0 beta3 (package included with Ubuntu Dapper Drake) and everything is working very well. Next I wanted to try the dovecot lda (for sieve filtering). In postfix I have "mailbox_command = /usr/lib/dovecot/deliver" and I followed the instructions from http://wiki.dovecot.org/LDA. I only changed "postmaster_address = postmaster@localdomain.local"

Hey Everyone, I'm pretty new at R and wanted to try and make some graphs with dummy data before using it to analyze my own. I successfully made a bar graph and error bars, but I can't figure out how to align them properly (currently they are not centered on the bars and some of them aren't even close). Here's the code that I'm using: > marks <- sample(4:10, size=50,
