Hi, I am a Rails noob. Suppose you have: --- class Animal < ActiveRecord::Base end class Mammal < Animal end class Cow < Mammal end --- 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...

...example here in cv.glm doesn't look right to me since it computes cv error over model trained on 100% of data.

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

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.

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...
