pseudo R-squared with likfit (geoR)
We want to compute a pseudo R-squared for a model whose parameter
estimation was based on maximum likelihood (function likfit, package geoR).
I tried to compute the R2 proposed by Maddala (1983) which compare the
maximized likelihood for the model without any predictor and the
maximized likelihood for the model with all predictors.
I got a really low value (0,01%). Did I miss something? Are

pseudo R-squared for model generated with spgm (splm)
I am working with the splm package. I use the spgm function: general
estimation of a panel data model. Based on this approach, I know it is
possible to compute a R2, eg the ratio of variation explained by a given
model.
My model is :
bivmod<-spgm(logIKA~NBLITRE0+NBLITRE1,data=mydatap,listw=comsKnn.nbW,spatial.error=TRUE)
I know that we can calculate the R^2 as the variance of the fitted

Samba as PDC and BDC on the same network.
I have recently configured two servers to be controlers of my domain.
The first one is the PDC and is configured like :
domain master = yes
prefered master = yes
local master = yes
domain logons = yes
security = user
os level = 99
And the second, the BDC like :
domain master = no
prefered master = no
local master = no
domain logons = yes

substring if value starts with a character
Hello togehter,
i have a litte problem to convert a data.frame. My data.frame looks like
this one
A
1 R5000
2 R4800
3 R4700
4 3500
5 3800
I need now a command, which outputs all the numbers, without the character
in front.
The solution look like this one:

3 4700

Thanks.
Best regards. Mat

Another loop avoidance question.
Hi
I want to sum over one of the dimensions of a n x k1 x k2 array in
which each column is the product of the corresponding columns from two
matrices with dimensions n x k1 and n x k2. I can see two approaches:
a loop on k1 and a loop on k2. But I cannot figure a solution that
avoids the loop? Is it possible? (I don't refer to apply or lapply etc
either as they are just hidden loops so,

About R variable references
Hello Group,
I could use an advice on how SEXP handles work. My aim is to implement a
system where I initially set a few global variables that are used for
communication between C and R code. Then I do some work with R code and
periodically call a function of my own that will update the system
state. Such a design is useful for many purposes (for GUIs to name one).
I am not entirely sure that R

Help with reading information of "summary"-Object

I tested all possible combinations of those variable and run for each

For some iterations, I got an error message: "error in kmeans(xx,

variable labels to accompany data.frame
Often it is useful to keep a "codebook" to document the contents of a dataset. (By "dataset" I mean
a rectangular structure such as a dataframe.)
The codebook has as many rows as the dataset has columns (variables, fields). The columns (fields)
of the codebook may include:
? variable name
? type (character, factor, integer, etc)
? variable label

can a class find out it''s instance name?
Hi friends - a javascript question....
Does the prototype object add some way for a class to find out the
variable name of its instance variable?
Or does javascript have some built in way to do this?
This is confusing to describe - but if I define a variable as some
object:
var myVariable= new Widget(''fdfa'');

Problem with effects package
Dear List,
Several times I use this package I get the error message shown below.
When I work out simple examples, it turns out to be fine, but when
working with real and moderate size data sets I always get the same

Do you know what could be the cause of the problem?

hierarchical partitioning
Dear all,
I am trying to model variation of distribution of species assemblages
according to environmental variables. For that I use a log linear
multinomial regression.
In order to select variables that mostly discriminate the assemblages, I
tried to apply a hierarchical partitioning protocol to my data set.
For that I have adapted the all.regs() for multinomial model.
The problem is that I

I’ve missed the discussions on file_time_type, however I thought I should throw in my opinion here before it is too late to do anything about it.
I believe it is a mistake to model file_time_type with 128 bits. It
