Hi all, I was wondering whether anyone could guide me to docu and code examples how to create and use a has_and_belongs_to_many relationship with a joining table where TWO columns are used to identify the relation to TWO alternative tables. Example: table 1: mothers [mother_id, name] table 2: fathers [father_id, name] table 3: children [child_id, name] joining table 4: children_parent

Hi, I am still new to R and have, in spite of searching all over, found no "understandable" documentation for how to join two (or more) frequency tables. Why would I want to do that and what do I mean by "joining" ? Let me try to explain: I have a diagnosis form that allows registration of up to three diagnosis codes on animals with birth defects, like this: father.id

Hi, I would like to create some S4 classes as follows setClass("Father",representation(name="character")) setClass("Son1",contains="Father",representation(par="numeric")) setClass("Son2",contains="Father",representation(par="logical")) Son1<-new("Son1") Son1 at name<-"Son1" Son1 at par<-3

Dear R mailing list, I have a dataset with genotypes from trios and I would like to infer haplotypes for each mother, father and child. The package that I could find that can do this is tdthap. But when the mother is homozygous (e.g., 2/2) the haplotype is called as not possible to infer (0); I would prefer for it to call the genotype (2). From what I understand it is doing what I would like

Faraway's book titled "Practical Regression and Anova using R", with full text available online at: http://cran.r-project.org/doc/contrib/Faraway-PRA.pdf refers to a data set, stat500, which compares midterm and final grades. It can be used to illustrate similar concepts. A google search for faraway.zip will locate the actual data. --- Date: Sun, 15 Feb 2004 10:37:08 -0800

Dear useRs, by a circular diagram representation I mean what you will get by entering this at your R promt: pie(1:5) Nice to have R as a lingua franca :-) The folowing quote is from page 360 in this very interesting paper: @article{SpenceI2005, title = {No Humble Pie: The Origins and Usage of a Statistical Chart}, author = {Spence, I.}, journal = {Journal of Educational and

I was reading through the FlexMock docs and noticed the expectation method .mock, which returns the original mock associated with an expectation. It looks really handy for writing nice all-in-one mocks like: mock_user = mock(''User'').expects(:first_name).returns(''Jonah'').mock So I started playing around with mocha and found I could actually already do this!

Using "winbind use default domain = <DOMAIN>" option usernames map correctly, however, when logging on from an W2K machine I still get the autogenerated UID instead of my NIS (Or /etc/passwd) UID. Both nis and files precede winbind in /etc/nsswitch.conf Commenting out winbind from /etc/nsswitch.conf works, which

I''m trying to get TPROXY / Squid running and I have a few questions...
