Cointegration Test in R
Hello!
I'm using the blrtest() function in the urca package
to test cointegration relationships.
Unfortunately, the hypothesis (restrictions on beta)
specifies the same restriction on all cointegration vectors.
Is there any possibility to specify different restrictions on
the cointegration vectors?
Are there any other packages in R using cointegration tests?
Thanks and best regards.

Methods not loaded in R-Devel vs 2.8.1
Dear list-member,
I am currently developing a package with S4 classes. The NAMESPACE and DESCRIPTION is printed below. Within this package I have set a method "residuals" for two classes. In version 2.8.1 these two are reported whereas in R-Devel (2009-01-28 r47766). What have I missed? What has changed and how can I rectify the issue? Your help and pointers are welcome.

memory.limit(): Typo in Windows NEWS and function returns a "disregarded" error
Dear list subscriber (R-Core),
there is a minor typo in the Windows specific NEWS for R 2.9.0:
http://cran.at.r-project.org/bin/windows/base/CHANGES.R-2.9.0
There is no function 'memory.limits() but memory.limit() (see below).
Secondly, I am kind of irritated by the function's behaviour. It returns an Error, but as it seems the memory limit is set according to the numeric value for

cointegration rank
Dear R - helpers,
I am using the urca package to estimate cointegration relations, and I
would be really grateful if somebody could help me with this questions:
After estimating the unrestriced VAR with "ca.jo" I would like to impose
the rank restriction (for example rank = 1) and then obtain the
restricted estimate of PI to be utilized to estimate the VECM model.
Is it possible?

R CMD Sweave versus Sweave() on Windows
Dear list subscriber,
I am quite puzzled by the behaviour of processing Sweave files within an R session, i.e.
Sweave("foo.Rnw") versus R CMD Sweave foo.Rnw
In the former the environmental variable 'SWEAVE_STYLEPATH_DEFAULT = TRUE' is obeyed (this is set in etc/Renviron.site as well as under the users home directory in .Renviron). That is the hard-coded path to Sweave.sty is

Sweave() within a function: objects not found
Dear list subscriber,
suppose, I do have a minimal Sweave file 'test.Rnw':

Within R, I define the following function:
f <- function(x){

The call:

Omegahat-site down?
Dear R-list subscriber,
is it possible that the omegahat-site is down? I was looking for package
'RDCOMClient', but could not establish a connection. In case somebody
has the latest binary zip-file for Windows, would she/he mind to send it
directly to my emaim adress stated in the signature?
Many thanks, and sorry for bothering/misusing R-help in this instance.
Best,

urca package - summary method -
Hi
I am using the package urca and I am interested about the KPSS test.
That works fine except the method "summary" did not work in the script,
only when it is typed direct in the console the results are shown( not a
source file).
Is there any problem with these method ?

Simulate values from VAR
Folks,
What is the best way to simulate values from a fitted "VAR {vars}" model.
Also I have tried to use SVAR for a cointegration fit of y~x (just two univariate time-series) but I can't figure out how to set up the "A" matrix so that x_t can be used as a contemporaneous predictor of y_t.
Thanks much for your time,

Best practices in developing package: From a single file
Dear All:
stepping in late, but @Joris, if you would like to take 'from a single file' literally,
have a look at:
https://github.com/bpfaff/lp4rp
(lp4rp: literate programming for R packages);
Cheers,
Bernhard
ps: incidentally, within the noweb-file roxygen is employed.

all.names() and all.vars(): sorting order of functions' return vector
Dear list-subscriber,
in the process of writing a general code snippet to extract coefficients
in an expression (in the example below: 0.5 and -0.7), I stumbled over
the following peculiar (at least peculiar to me:-) ) sorting behaviour
of the function all.names():
> expr1 <- expression(x3 = 0.5 * x1 - 0.7 * x2)
> all.names(expr1)

The weak exogeneity test in R for the Error Correction Model?
Hello all,
I would like to carry out a single-equation approach of the Error Correction Model such as
Delta_y(t) = a + b*y(t-1) + c*x1(t-1) + d*x2(t-1) + e*delta_x1(t) + f*delta_x2(t) + epsilon(t)
Where, a, b, c, d, e, f are coefficients to be estimated, y is the dependent variable, and x1, x2 are independent variables.
For the single equation approach of ECM, there is a requirement of the

Question on Simultaneous Equations & Forecasting
Frances,
I would not advise Gauss-Seidel for non linear models. Can be quite tricky, slow and diverge.
You can write your model as a non linear system of equations and use one of the nonlinear solvers.
See the section "Root Finding" in the task view NumericalMathematics suggesting three packages (BB, nleqslv and ktsolve). These package are certainly able to handle medium sized models.

Who was speaking about non-linear models in the first place???
The Klein-Model(s) and pretty much all simultaneous equation models encountered in macro-econometrics are linear and/or can contain linear approximations to non-linear relationships, e.g., production functions of the Cobb-Douglas type.

COM objects with early bindings in R

I am using the packages RDCOMClient and SWinTypeLibs and try to import a COM
