Logistic Regression with genetic component
Greetings, I have a question that I'd like to get input on. I have a classic toxicology study where I artificially fertilized and exposed embryos to a chemical and counted defects. In addition, I kept track of male-female pairs that I used to artificially fertilize and generate embryos with. I need to use logistic regression to model the response, but also check that the genetics of the pairings did or did not have an effect on the response....

Multivariate binary response analysis
Greetings ~ I need some assistance determining an appropriate approach to analyzing multivariate binary response data, and how to do it in R. The setting: Data from an assay, wherein 6-hours-post-fertilization zebrafish embryos (n=20, say) are exposed in a vial to a chemical (replicated 3 times, say), and 5 days later observed for the presence/absence (1/0) of defects in several organ systems (yolk sac, jaw, snout, body axis, pericardial edema, etc.) for each fish. The assay can be used as a screen (in which case a single...

aggregate and names of factors
Hello, I use the function 'aggregate' a lot. One small annoyance is that it is necessary to name the factors in the 'by' list to get the names in the resulting data.frame (else, they appear as Group.1, Group.2...etc). For example, I am forced to write: aggregate(y,list(f1=f1,f2=f2),mean) instead of aggregate(y,list(f1,f2),mean) (for two factors with short names, it is not such

Parsing issues
I''m running into a very odd occurrence. I started with a new puppet server and was able to add a few classes, however as I try and add new ones I get odd parsing error messages, the most common being Could not match ''}'' at whatever file. Here is the exact error I get err: Could not retrieve catalog: Could not parse for environment production: Could not match

Solaris package woes
I am trying to get Puppet to push out a Solaris sudo package that I built, but I keep getting errors. I tested applying the package manually outside of Puppet and it works perfectly, but when I attempt to push it out via Puppet it fails. Puppetmaster Version: 0.23.2 [Ubuntu Linux 7.10 - Puppet built from source] Puppet client version: 0.23.0 [Sun Solaris 10 Zone - Puppet built from source] The

How do I compare 47 GLM models with 1 to 5 interactions and unique combinations?
Hi R-listers, I have developed 47 GLM models with different combinations of interactions from 1 variable to 5 variables. I have manually made each model separately and put them into individual tables (organized by the number of variables) showing the AIC score. I want to compare all of these models. 1) What is the best way to compare various models with unique combinations and different number
