help, bifurcation diagram efficiency
Hello all - This code will run, but it bogs down my computer when I run it for finer and finer time increments and more generations. I was wondering if there is a better way to write my loops so that this wouldn't happen.

bifurcation countings in a cluster dendrogram
...uite new working with R, and that might be a very easy question for some of you. So I hope you can help me!! I used a hirarchical cluster analysis to create dendrograms, like that: hc <- hclust(dist(USArrests), "ave") plot(hc) plot(hc, hang = -1) Here I want to compare the number of bifurcations for each species, but therefor I need this numbers first. There should be an elegant way to get this- instead of counting everything. I would be happy if you could tell me the solution!!!! Thanks a lot in advance!!!

Bifurcating Autoregression
Is there any R package that implements a bifurcating autoregression, aka the BAR(n) model? I've been reading the Huggins and Staudte paper, "Variance Components Models for Dependent Cell Populations", from the Journal of the American Statistical Association, 1994.

KISS and DRY? Not even close!
Hi all, After working on my first rails app and having handed over some very sophisticated coding from a lot of you guys. My app does what I want it to do, but I''m no where near the end yet, and it seems that the KISS and DRY objectives already went down the drain. It could be lack of knowledge, only doing Ruby on (and) Rails for a month, but I''m stuck on the following:

Child record becomes orphan
Hi all, I''ve got these company (has) contacts relational tables. I want to make sure a company can''t be deleted when it still has contacts. (because I can now, which results in nil like errors when listing the contacts ... obviously) Are there any helpers to do so, is Rails aware of this? Or do I need to put in a condition before destroying the company record in question

NoobyQ: how to work with a table of static lookup data??
Hello out there! Nooby question: What''s the "Rails" way to work with tables of relatively static lookup data? Objectively (I''m thinking); I don''t want to hit the DB each time, so for each lookup table, initialize a globally available hash with lable/value pairs... Am I on the right track? How would you do this kind of thing in Rails? Thanks! --

For an unknown reason, the primary key (id) of the child table is not automatically increased.

Generating nice tables
Making tables in templates is pretty easy, except for one minor problem. They tend to be fairly ugly. If you have a model with three attributes, it''s very easy to create an html table that looks like this.. Col1 Col2 Col3 A B D A B E A C F A C G Which becomes difficult to read when you have a lot of repeated data. What I would really like to generate
