similar to: query string parsing C extension

Hi, [I sent this to the plyr mailing list (late) last night, but it seems to be lost in the moderation queue, so here's a shot to the broadeR community] Apologies in advance for being more verbose than necessary, but I'm not even sure how to ask this question in the context of plyr, so ... here goes. As meaningless as this might be to do with the `iris` data, the spirit of it is what

I got sidetracked while benchmarking ruby factorial code: http://rosettacode.org/wiki/Factorial#Ruby I put all that code into test_fact.rb and ran with: > ruby test_fact.rb > rails runner test_fact.rb #from a fresh rails app > rails runner test_fact.rb #from a mature rails app here are the respective results: user system total real #ruby recursive:

I am trying to add data from a form, and the rails doesn''t appear to be making any effort at all. I''ve put deliberately erroneous data, but still nothing. All the development log shows is this.

Dear list, I have been searching for a week to fit a simple linear model to my data. I have looked into the previous posts but I haven't found anything relevant to my problem. I guess it is something simple...I just cannot see it. I have the following data frame, named "data", which is a subset of a microarray experiment. The columns are the samples and the rows are the probes. I

Dear friends, when i use glm() to fit my data, i use glm(formula = snail ~ vegtype + mhveg + humidity + elevation + soiltem, *family = Gamma(link = inverse),* data =a,)) It shows: error in eval(expr, envir, enclos) : *gamma distribution don't allow negative value*. But i use result<-glm(formula = snail ~ vegtype + mhveg + humidity + elevation + soiltem, family = poisson, data =a) #this

I have no idea why this is happening but it seems like every method on my controller gets called twice. Here is what it looks like when I call a list using the scaffold code ========================== Processing DepartmentsController#index (for 127.0.0.1 at 2006-02-24 01:05:00) [GET] Parameters: {"action"=>"index", "controller"=>"departments"}

Hello everyone, I have a corrupt .vdi file from a virtualbox installation (XP host, Mint 11 guest) which I recently broke.
