Single Table inheitance doesn''t show subclasses ?
...I provide Animal,Mammal and Cow controllers with the scaffolding, just to test and to fill up the Animal table. I can see the "type" column getting it''s value set with the class name. So far, soo good. Now, since listing Animals is showing all animals in the table (including Mammals and Cows) i thought that listing Mammals would show me all Mammals *and* Cows, but i see only recods marked "Mammal" in the "type" column (and no Cows). I understand that Rails doesn''t select descendants of a class when listing it''s elements, and i understa...

GLM with regularization
...example here in cv.glm doesn't look right to me since it computes cv error over model trained on 100% of data. (e.g. wikipedia crossvalidation article lists this as an example of misuse of K-fold CV). ----- doc quote ---- # leave-one-out and 6-fold cross-validation prediction error for # the mammals data set. data(mammals, package="MASS") mammals.glm <- glm(log(brain)~log(body),data=mammals) cv.err <- cv.glm(mammals,mammals.glm) cv.err.6 <- cv.glm(mammals, mammals.glm, K=6) ---- end of quote --- Those seem to be pretty common techniques, any poniter in the right direction...

Subset with selection variable from function argument. Is there another way?
Dear list, I'm making my current code more generic and would like some advise. The basic problem is subset and the name of the column to be compared for selection. What I've come up with is > data(mammals) > set <- bottompremolars" > subset(mammals, eval(parse(file="",text=set)) > 2) This seems a bit odd. Is there a nicer way? /Fredrik

Gamma & Lognormal Model
Dear, I'm very new to R Gui and I have to make an assignment on Gamma Regressions. Surfing on the web doesn't help me very much so i hope this forum may be a step forward. The question sounds as follows: The data set is in the library MASS first install library(MASS) then type data(mammals) attach(mammals) Assignment: Fit the gamma model and lognormal model for the mammals data. I appreciate any help you can provide. Best Wishes, Louisa -- View this message in context: http://r.789695.n4.nabble.com/Gamma-Lognormal-Model-tp3165408p3165408.html Sent from the R help mailing lis...

PCA analysis, presence-absence of mammals in parks
Hi everyone, So I am trying to see which ecological parameter of different parks in nyc influence the most the diversity of the medium-sized mammals in those parks. I have a bunch of different parameters for each park I'm done studying and the presence (1) and absence (0) of each mammal. I wanted to do a principal component analysis of those data to know which ones of those parameters are the most important. Here is what I have: Parc...
