Problems with Unit Root testing using ur.df function
Hi All,
I'm new to R and am trying to run a unit root test on the vector "y" (a time
series of inflation (i.e. changes in the Consumer Price Index quarter on
quarter)).
I've run the Augmented-Dickey-Fuller Test below (R's URCA package). It gives
me an error that it cannot find the function ur.df unless I comment out the
third last line of code (see below).

Creating timeSeries
Hi
I want to create a TimeSeries object with already defined dates (in the
first vector) so that all the data are coerced as a time series object with
the dates as they are.
Is there anyone that have an idea what to do?

ZA unit root test lag order selection
I was wondering if anyone could help with choosing optimal lag length for ZA
test.
There have been two lag order selection methods commonly used in the
literature:
1) The ZA paper recommends to run the test with maximum number of lags. Then
the lag order is reduced sequentially until the longest lag is statistically
significant;
2) One could also use AIC or SBC or other criteria to choose lag

Register Number
Dear all,
in my TestRegisterInfo.td file, I defined a register like this:
class TestReg<bits<6> enc, string name> : Register<name> {
let HWEncoding{5-0} = enc;
let Namespace = "TEST";
}
def D0 : TestReg<0x01, "d0">, DwarfRegNum<[1]>;
but when I compile, the result I have in TestGenAsmMatcher.inc is this:

WG: Formal methods are not loaded from NAMESPACE inreloadedworkspace image
Sorry, to bother the list one more time: but the following worked at
least for 'urca':
in NAMESPACE I now included explicitly:

a fix of the 'urca'-package will be uploaded to CRAN on the weekend.
Fritz, will this work for ypur package 'flexclust' too? I have in my

Question about TableGen RegisterClass definition
Hi All,
I have a question about TableGen RegisterClass definition.
I need to map different size of MVTs into a register class as below.
def TestReg : RegisterClass<"Test", [v8i32, v4i32], ...>
When I look at TableGen and CodeGen, it looks the types are used as following:
1. MCRegisterClass's RegSize and Alignment
2. SpillSize in TableGen
3. Type constraint for instruction

Formal methods are not loaded from NAMESPACE in reloadedworkspace image
Dear R-Devel subscriber,
as a follow up to my yesterday's email: I tested an analogous example
with the S4-package "flexclust" by executing the following code:

example(cclust)

After saving the work space and starting a new R process with the
restored work space, the same behaviour (i.e., the methods pertinent to

summary method in URCA package doesn't work
I can't figure out how to get the "summary" method in the URCA package to
work.
E.g. when I use the following code fragment in the help for the "ca.jo"
function,
it always tries to use the "summary" method from the "base" package,
not the "urca" package.
How do I force it use the "summary" method of the "urca" package?

can't write Samba share as anonymous
I'm not sure I have understood, I'm mounting the share as "urca" user,
which is not a known user.
Although I'm setting smb.conf so that for guest user it uses the
privileges of the known user "andrea"
Could you please advice on what I should set for "guest account" in
smb.conf?
Thanks

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

Is there any problem with these method ?

VECM with UNRESTRICTED TREND
Dear All,
My question is:
how can I estimate VECM system with "unrestricted trend" (aka "case 5")
option as a deterministic term?
As far as I know, ca.jo in urca package allows for "restricted trend"
only [vecm
<- ca.jo(data, type = "trace"/"eigen", ecdet = "trend", K = n, spec =
"transitory"/"longrun")].

Coefficient names when using lm() with contrasts
Dear R Users,
Am using lm() with contrasts as below. If I skip the contrasts()
statement, I get the coefficient names to be
> names(results$coef)
[1] "(Intercept)" "VarAcat" "VarArat" "VarB"
which are much more meaningful than ones based on integers.
Can anyone tell me how to get R to keep the coefficient names based on the
factor levels

Cointegration and ECM in Package {urca}
Dear R Core Team,
I am using package {urca} to do cointegration and estimate ECM model,
but I have the following two problems:
(1) I use ca.jo() to do cointegration first and can get the
cointegration rank, alpha and beta. The next step is to test some
restrictions on beta with blrtest(),bh5lrtest(), and bh6lrtest(). But
none of them can add restrictions on all the cointegration
