Hello All, I am looking for an R library/function that allows the specification of a custom link function in a linear mixed model. I've been using glm() in library MASS to fit fixed-effect models with a custom link but my study design demands mixed models. Any suggestions on the best R library/function to achieve this would be greatly appreciated. I have tried, to no avail, to

Hi, does anyone know how to make pairs of boxplots? E.g. 5 pairs of boxes. I figured a not very elegant way, by inserting a dummy NA field to the list where the data is given. So, where I have the dummy I got more distance between boxes, as a result it looks like groups. But I am having problems with putting the names under the groups, and the thick marks. Any better idea? Thanks, Kati ___

Dear All, I need to calculate the variance components in a mixed effect model (one fixed and one random effect) with REML (maximizing the proportion of the likelihood that does not depend on the fixed effects). In S+ there is the varcomp function, but I would like to do it in R. Is there a way to do that? Thanks! Katalin ___ Katalin Csillery Division of Biological Sciences University of

Hi, I have a coding problem. I have data pairs, and I want to calculate a parameter for the data pairs as a whole data set (so not using the information that thely are pairs) I am looking for bias in that certain parameter so I want to bootstrap these data pairs(!), and than calculate the parameter. I run into a coding problem. How should I define theta in order to resample the pairs, but than

Dear All, I am trying to use the bca.ci function on a boot.out object which consists a few NaN's and I want to ignore those NaN's, and get a ci only for the "normal" values. boot.out$t has R number of values for 3000 different statistics, so when I use boot.ci(boot.out, index=i) and i happens to be a column in boot.out$t with some NaN's in there I get an error message. I

I posted this late yesterday afternoon to no response, so I figured I''d try once more to get the morning people''s attention. I''m working on setting up the credit card processing part of a rails app for my company and running into some issues. I''m currently working with the ActiveMerchant plugin and connecting to our account at Authorize.net.

Dear All, I have a function which takes a n x m matrix as an argument and returns an n x n matrix. I want to take bootstrap samples form the input matrix in the way as each row represent a multivariate observation, so each bootstrap sample would be an n x m matrix, and on each sample I want to calculate the n x n matrix. This task can be done with the sample function, but I would like to use

Any Rails Developers in Montana? Especially Helena or Bozeman? I don''t expect there''s enough of us to form a user group, but it might be nice to talk shop ''offline'' every once and a while.

I am having a problem with doing a :through that goes back to the same table. The following are my two classes: >>>>> class User < ActiveRecord::Base has_many :spanks has_many :spanked, :through => :spanks, :source => :spanked_user has_many :was_spanked_by, :through => :spanks, :source => :user end class Spank < ActiveRecord::Base belongs_to :spanker,

Does anyone know how to coerce a list to an array? I have a list with equal sized matrixes and I want to coerce it to a 3D array. Why is that that I cannot feed in equal sized matrixes as layers to an array even if I set dim 3? Thanks!

Hello, I want to bootstarp a sample, and I need table() for each sample taken, like if R=100, I need all 100 table(). It seems to mee that boot() works anly if you assing statistics, that gives you back one number, like mean. Although the ?boot/statistics says that it can be a vector containing statistics. table() gives an array, so it might work. Does anybody have an idea how? I konw it can be

Hello, I am interested in fitting a generalized nonlinear regression (gnlr) model with negative binomial errors. I have found Jim Lindsay's package that will do gnlr, but I have having trouble with the particular model I am interested in fitting. It is a threshhold model, where below a certain value of one of the parameters being fitted, the model changes. Here is a sample: Cones:

Hi, I am trying to get into this REST thing, I have a nested resource whith the following route: ActionController::Routing::Routes.draw do |map| map.resources :members map.resources :clubs do |club| club.resources :members end map.connect '':controller/:action/:id'' map.connect '':controller/:action/:id.:format'' end Everything worked ok for this

Given the following.. Foo has_many :bars Bar has_many ::widgets Widget has_many :gadgets Gadget has_many :parts All of the following are now possible... @foo.bars @bar.widgets @part.gadget.widget.bar.foo However, I can''t just do the opposite of that last one... @foo.bars.widgets.gadgets.parts and get a full list of every Part associated with @foo. I know there''s several

Hi, I have a function which does a certain task with two vectors, f1 <- function(a,b){body} I also have a list of matrixes (all with the same dim's), and for each column of each matrix in the list I want to use "f1", in such way that it gives the vector "a" in the first argument of "f1". The second argument of the function "b" also comes form a

We spent a big chunk of yesterday hunting down a strange bug in one of our rails apps and created a test project to try out different theories on what was going on. The result so far is a very small test case app that perfectly reproduces the problem. The question is, is there anything *wrong* with what we''re doing here, or is it a problem with ActiveRecord? We''re on rails

I was wondering if there is a way to monitor and gather metrics for Samba. We would love a solution that would be able to plot the number of connected users, file usage, samba server load, etc. Does anyone have any of these tools or any suggestions? Something similar to smbstatus but with more information and the ability to output (for graphing and logging). -marc
