Problem with accessing internal variable in package.
I am writing a package, which contains several functions and variables.
The variables are for internal use by functions.
Functions are ment to be callable by a user.
However, the function cannot access these variables.
The package contains only R code, and was created using package.skeleton
package.skeleton(name="ac9",
list=c(ls(pattern="(AB2)|(ac9)"),

private variables in package.
I am sorry, my previous questions about hiding variables from users in a
package were obscure and vague, and would like to clarify them.
This should be a basic question.
I am writing my first package.
It has several functions, which should be callable by users.
These functions use several variables, and I would like to hide these
variables from users.
How can I do it?
For example, the package

Updating R-Software without complete new installation
Hallo,
as I see there is a new version for R available. Can anyone tell me how
I can update my version 2.5.0 under Windows? The last times I just
uninstalled the old version and installed the new one. Afterwards I had
to install also all needed packages again. All in all it cost me half a
day until my system works fine again. Is there a quicker option? If yes
please tell me the commands.
Thanks,

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!

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:

how to image.plot a XY grid file into a lat-lon map
Hi All,
I have a netcdf gridded file with LCC projection. I can easily use
image.plot to visualize it. However, as the axises are in X,Y, not Lat and
Lon, I could not add state or country maps onto it (or lat lon information).
I do have a grid2d file that describes the lat and lon for each (X,Y) grid,
but the lat and lon are not regularly spaced, so I could not use image.plot.

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)

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:

several regression lines in panel of xyplot (trellis graphics)
Dear r-help,
I need to draw xyplot() graphs with several regression lines:
one line for the whole range of x (the variable on the horizontal
axis) and two additional lines for subranges of x.
Is it possible to make first regression line (panel.lmline(x,y,...);)
to be drawn on the whole graph
and regression lines of the subsets to be drawn only over their subsets?

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

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")
Coefficients:

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()
