correlated random effects in GLMMGibbs ?
Dear R-users,
I wondered if anyone has extended GLMMGibbs to include correlated
random effects, and if so, whether they would be willing to let me
use their code?
Jonathan Myles has no plans to extend glmm in this manner within the
foreseeable future.
With thanks,
Patty

BATCH mode
Dear R users
I wonder if it is possible to run R code in the batch mode like in Splus
(Splus5 scriptfile outputfile).
Any hints?

Problems with mock assigned to a constant
Hi all,
Initially I thought this was a bug in the built-in mocking framework(and it
still may be), but I better hash it out on the mailing list before I
file/reopen the ticket:
http://rspec.lighthouseapp.com/projects/5645/tickets/478-mocks-on-constants#ticket-478-6
I thought my example illustrated my problem, but obviously I was passing the
wrong arguments to the mock. I revised my example to

Calculating AIC for the whole model in VAR
Hello!
I am using package "VAR".
I've fitted my model:
mymodel<-VAR(mydata,myp,type="const")
I can extract the Log Liklihood for THE WHOLE MODEL:
logLik(mymodel)
How could I calculate (other than manually) the corresponding Akaike
Information Criterion (AIC)?
I tried AIC - but it does not take mymodel:
AIC(mymodel)
# numeric(0)
Thank you!

Simon Wood GAMsetup
Dear Simon, Thank you for your quick reply!
I used to perform the GAMsetup in the following manner:

Exporting to text files
I have dose response data analyzed with the package 'drc'.
'summary(mymodel)' prints my kinetic parameters. I want
that text in an ASCII text file. I want to get exactly what I
would get if I copied and pasted from the terminal window.
I've read the documentation on data export to text files here:

dynamically adding static (class) methods to a class
Hello again,
I guess this is more of a Ruby question, but here goes anyways...
I want to intercept all calls to non existent class methods and then
call an existing class method with the non existent name.
In code...
class MyModel < ActiveRecord::Base
def MyModel.method_missing(symbol, *args)
MyModel.func(symbol.id2name)

import data from splus
hi there,
anybody knows how to import data into R from splus directly? I have a huge
amount of data in splus format, which will cost forever for me to transform
the data back to ascii or something else and then read them into R.
thanks a lot.

Questions bout SVM
Hi everyone,
Can someone please help me in these questions?:
1)if I use crossvalidation with svm, do I have to use this equation to calculate RMSE?:
mymodel <- svm(myformula,data=mydata,cross=10)
sqrt(mean(mymodel$MSE))
But if I don’t use crossvalidation, I have to use the following to calculate RMSE:
mymodel <- svm(myformula,data=mydata)

Referring to an object name from within a function
Can anyone show me how to refer to an object name that is passed to a
function, from within the function?
For example:
MyModel <- 1
test <- function(x) {
if(x == 1) {cat("x is a valid object.\n")}
}
test(x)
What I would like this to do is pass MyModel to function test, and if it
passes a test, be able to print "MyModel is a valid object."
Thanks.

Can''t disable ferret when running in Mongrel
In my environment.rb I say the following:
MyModel.disable_ferret
puts MyModel.ferret_enabled?
The console works as expected:
script/console
false
>> MyModel.ferret_enabled?
=> false
I can then edit an instance, ferret remains disabled and the changes
are not immediately indexed.
However, when I start mongrel Ferret is initially disabled, but then
somehow becomes enabled again

Predictions with missing inputs
Dear users,
I'll appreciate your help with this (hopefully) simple problem.
I have a model object which was fitted to inputs X1, X2, X3. Now, I'd like
to use this object to make predictions on a new data set where only X1 and
X2 are available (just use the estimated coefficients for these variables in
making predictions and ignoring the coefficient on X3). Here's my attempt

Problema con la función lm

Tengo un determinado código en R que en una máquina funciona correctamente, pero en otra devuelve un error del tipo "Error en as.formula(mymodel): Objeto ''mymodel'' no encontrado''"
En mi código:

How to extract vectors from an arima() object and into a data frame?
This should be very easy, but alas, I'm very new to R. My end goal is to
calculate p-values from arima().
Let's say I just ran this:
> MyModel <- arima(y[1:58], order=c(1,0,0), xreg=MyData[1:58,7:14],
> method="ML")
> MyModel
And I see:
arima(x = y[1:58], order = c(1, 0, 0), xreg = MyData[1:58, 7:14], method =
"ML")

Offline indexing issues
If I disable ferret in my environment file and then run a cron job
every hour to index the records that have been added/changed, do I
enable Ferret just in the script that does the hourly indexing? Or do
I somehow need to tell the process that runs the Ferret DRB server
that it should start writing to the index again? Thanks in advance.

how to debug (mtrace) a function defined inside a function?
Hi, everyone. I am using a fair amount of closures in my code. Problem i am
experiencing is i cannot figure out how to mtrace functions defined within a
function. There must be some way to name such function for mtrace to see it
and let me step into it. For example, say i have code
mymodel<-function(){
data<-numeric(0)
build<-function(){
data<<-1
}
m<-list()
