Thanks a lot Wacek for this clear description of the problem - I was
not aware, that it is that complex.
I definitely did not consider the initialize() function in writing my code.
But as I only want to allocate the space for the objects, it does not
matter here. But when I write a simulation and

The answers differ by a factor of 19/20, ie, (n-1)/n, so it is presumably
the choice of denominator for the variance that differs.
Same issue is present in ccf():
cov() != ccf(lag.max=0, type=covariance).

Dear all,
I am having a problem downloading webpages through R when i run it in
the DOS window under Windows Vista Basic. I have downloaded the
batchfiles from http://code.google.com/p/batchfiles/ and have
successfully set the PATH.
I open up 'Command Prompt' in Vista and type (after the C:\...
Hi,
Let theta be the coefficient in AR(1) model, the components of the correlation
structure is equal to 1 for times s = t, and theta^|t-s| for t s.
Could someone do me a favour to give some ideas on the correlation structure in
AR(2) model and correlation structure of ARMA(p,q), as well?
dear,
I am trying to plot a standard plot, but I want the x axis to be 1,2,4,8,16
with equal intervals between them on plot.
I will appreciate some help.
Thank you,
Irina

Hi Gabor,
Thank you kindly for your response.
Re: Don't need to set PATH -- When I read the batchfiles page, the
opening paragraph says just place any or all of them anywhere in your
Windows path and you will be able to access them in any Windows
console session. My interpretation of this was

Did you perhaps get an undesired doubling of !?

Is this the intended behavior?
In general, all.equal is strict about argument mode, thus TRUE/1 and 1/'1'

I'd like to perform return variable assignments like matlab. For example,
the following function would return A, B, and c to the script that called
it.

function [A,B,c] = simple(m,n)
A=[ 3 2; 3 3]
B=m
c=1:n
