similar to: Can I use "lme" to deal with grouping data when I only get one data point per group?

What would be the best away to go about group results. For example: two children contain the word "test" how would I get it to just display its Parent once? Thanks for the help! -- Posted via http://www.ruby-forum.com/.

I remember reading something awhile back about an easy way to work with object arrays in views. Say I want to arrange 20 images objects in rows of 3. I have a collection of @users, where each user has a user.thumbnail_url image. Is there some way to split these up so that they can be easily parsed in rows of three? Thanks, Nathan -------------- next part -------------- An HTML

Hey all - New to Ruby, though I''ve managed to stumble around in PHP (well, enough to hack together what I needed). I''ve initiated a (hopefully) simple project to keep track of upcoming stories in our newspaper. It''s a one-table database with just a few fields (writer, publication date, synopsis, notes, page assignment). I''m slowly replacing the default

Hi all, it''s my first time posting on the list - this is something I couldn''t find anywhere else If I create two models, using ruby script/generate model foo/bar ruby script/generate model baz/bar then the generator has no problem making app/models/foo/bar.rb and app/models/baz/bar.rb, however the migrate files it creates both try to "create_table :bars" I thought

Hello, I''m running puppet 0.22.4 on redhat linux mainly. I have a large number of hosts and after reading the documentation, I concluded the following; It would be easier to manage all nodes by creating a class called common which in turn imported files from common/*.pp, and one class for server, which inherits common, and in turn imports files from servers/*.pp (and then a class called

This more of a best practices question. I''m implementing group functionality in a couple of applications. The typical method, using HABTM, where you create a group and add members, is typical. For example, Users, Groups and Messages. Does anyone prefer tagging instead? Any advice would be great! -- Lon Baker http://www.speedymac.com AIM: spdemac

Hi, I am a new comer to R. I want to carrying out some exploratory data analysis on some financial data which has been time stamped.

Hello, I am currently using probplot function in the e1071 package to do cumulative probability plots . I want to be able to do multiple cumulative probability plots ( based on a grouping of data) on a single plot. Any help with this would be greatly appreciated. Thanks.

I try to display the grouping variable in coplot. It work, but it's special solution and rather ugly. Any better idea? # Simulate my data frame data(state) x77<-data.frame(state.x77) x77$region<-state.region coplot(Life.Exp ~ Income | region, data=x77, show.given=F, subscripts=T, panel = function(x, y,subscripts, ...) { panel.smooth(x, y, span = 1., ...)

Does ZFS currently attempt to group metadata in large sector-ranges on the disk? Can this be expected to happen "automagically" - i.e. during each TXG close we have to COW-update whole branches of the blockpointer tree, so these new blocks might "just happen" to always coalesce into larger sector groups? Rationale: larger regions dedicated to smallish block pointers might be

Dear all I have a question regarding repeating a series of nested ANOVAs. The model is: fit <- aov(response ~ treatment + plot/rep) Treatment has three levels, there are three plots and each plot has four replicates. Now, the experiment was also repeated six times during the year. Ideally I would have liked to include sampling time (month) as an additional factor in the analysis, but

Hello everybody 1. If there is/ever will be a function to perform "duncan multiple range test" please inform me at once. 2. Is there a way to create a grouping as duncan does from TukeyHSD output? My experimental design contained 62 genotypes, so the pairwise comparison is not that usefull and clear to look at. How would I do that? Is there an other test that does give grouping as
