I know it isn't done often, so apologies if this posting offends. But after posting the announcement of the open position to a number of other software lists, I was thinking, why not to R-help? (esp since knowing R is one option for meeting the requirements). best, -tony We are looking for an masters level statistician. If interested, feel free to apply. I am available to answer

Hi All, I'm trying to modify some of the default graphic parameters in a conditional histogram. While I was able to change the default grey background to white, I couldn't change the axis.font or the xlab font. I used the following code: /histogram(~V751|V013+V025, finalbase, xlab="Heard of HIV/AIDS (No/Yes)", col=c("cyan","magenta"),

Hello, I have a dataset containing approx 1000 events spanning four years (2004.03 to 2008.07). For each event, I'd like to determine the time (in minutes) since the most recent final Wednesday of the month. I've found no obvious solution on the list or online; I think I'll try to use functions in the chron package. Anyone have any other advice? Thanks. M-J School of Population

I am trying to set up a data set for a survival analysis with time-varying covariates. The data is already in a long format, but does not have a variable to signify the stopping point for the interval. The variable DaysEnrolled is the variable I would like to use to form this interval. This is what I have now: ID Age DaysEnrolled HAZ WAZ WHZ Food onARV

Hello all, I have two problems with the ROCR package.

R 2.7 Windows XP I have two model that have been run using exactly the same data, both fit using glm(). One model is a linear regression (gaussian(link = "identity")) the other a quasipoisson(link = "log"). I have log likelihoods from each model. Is there any way I can determine which model is a better fit to the data? anova() does not appear to work as the models have the

I like the concise version of stubs available on true mocks: => #<Mock:0x32f76d4> >> foo.stubs(:one => ''hi'', :two => ''again'') => {:one=>"hi", :two=>"again"} Why can''t we do it on ''real'' objects? >> foo = Object.new >> foo.stubs(:method1 => ''a'',

FYI - I''ve just released Mocha 0.5.6 to make Ruby 1.9 compatibility fixes available for those using released packages rather than subversion trunk. I''m not feeling well and so haven''t been able to test it other than by running all the tests using Ruby 1.9. Please let me know if you have any problems using it. Remember that it sometimes takes a while for a new gem

I happened to mix ryan bates'' authentication scaffold with rspec_scaffold on a demo project. and ran into the problem of mixing mock frameworks...ryan uses mocha. So, as a learning experience, I choose to redo ryan''s tests without mocha but ran into a strange problem with tests of the User model. With debugging you can see.... If you run just the user_spec.rb file, everything

Dear colleagues, I'm conducting a meta-analysis of studies evaluating adherence of HIV-positive drug users into AIDS treatment, therefore I'm looking for some advice and syntax suggestion for running the meta-regression using proportions, not the usual OR/RR frequently used on RCT studies. Have already searched already several handbooks, R-manuals, mailing lists, professors, but... not

Hi, (Mocha and Stubba are great, btw.) Is there any way to alias the call to .type in Mocha? The issue is that AR effectively aliases the normal type method for the Column class (for whatever Adapter.) My code is reflecting on the adapter methods to iterate over the columns in a particular model. This makes it hard to write test code that stubs out columns and mocks my models. E.g. cols =

I really like the idea of Mock Proxies as explained in Brian Takita''s post here: http://pivots.pivotallabs.com/users/brian/blog/articles/352-introducing-rr I posted to this list eariler with an incomplete implementation of .stops_mocking in the thread "Mocking Time, delegating to original object." The Mock Proxy pattern would make this simpler.
