ur.df ADF Unit Root Test: what is the meaning of phi1 and phi2 test statistic?
Hello,
I am using the ur.df function from the {arca} package to run the augmented
Dickey-Fuller unit root test on several time series. However; I do not
understand the econometric interpretation of the the "phi1" and "phi2"
test-statisitc which are output if you choose a "trend" or "drift" model. I
looked at the source code for the function but I do not

[Fwd: Excluding data with apply]
Dear all,
I've got many responses to my initial question, which is stated below.
However, from those responses it has become clear that I need to
rephrase my problem. All responses dealt with subscripting the data
matrix before 'apply' is run on it. But this is not want I wanted to do.
'apply' cycles through rows or columns of a matrix, and runs a function
on each row or

No fonts control on Cairo in batch mode
Dear all,
I am using Cairo version 1.4-5 for plotting R graphs on a Gentoo system
that does not have X11 installed. I have full control on the fonts when
running R in interactive mode. But when running R in batch mode I cannot
change e.g. font size. Letters (including symbols) are, however, drawn.

Debian (but still Linux):

custom route for forwarded traffic
Hi,
I have two networks, users and servers connected via vpn (ipsec). Both
internal networks. The routing is fine and connections work both ways.
Accordingly both networks have a firewall each which faces the internet
and they create the vpn link between each other. Both firewalls have
only one external IP (if they had more, I wouldn''t be asking).
The servers network''s

Significance of Principal Coordinates
Dear all,
I was looking for methods in R that allow assessing the number of
significant principal coordinates. Unfortunatly I was not very
successful. I expanded my search to the web and Current Contents,
however, the information I found is very limited.
Therefore, I tried to write code for doing a randomization. I would
highly appriciate if somebody could comment on the following approach.

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).

gnls - Step halving....
Hi all,
I'm working with a dataset from 10 treatments, each
treatment with 30 subjects, each subject measured 5
times. The plot of the dataset suggests that a
3-parameter logistic could be a reasonable function to
describe the data. When I try to fit the model using
gnls I got the message 'Step halving factor reduced

question about function "gls" in library "nlme"
Hi:
The gls function I used in my code is the following

My question is how to extact the AR(2) parameters from "fm".
The object "fm" is the following. How can I extract the correlation parameters
Phi1 and Phi2 from "fm"? These two parametrs is not in the "coef" componenet of "fm".

dealing with package bundles (was RE: Gregmisc)
Given the confusions that some users have regarding package bundles, I'd
like to suggest some changes to how package bundles are handled.
My understanding is that a package bundle is essentially a convenient way to
distribute related packages, so that users can download/install them in one
shot. However, some users apparently get confused that one can do
