2. the time as the number of milliseconds elapsed since hour 00:00:00.000 of
this date.
My question is :
1. Is there a in built function that can give me the
Yes it was what I was after ... sorry should have looked again.

Hi guys,
I have the following problem : when plooting using the X11() device, the
output I get is different from the output I get when I use pdf().
For instance the title font size in a pdf seems to be proportionnaly bigger
that in a x11...
I tryed to set pdf.options() egal to x11.options(),

Hi guys,
I am trying to shift down the ylab of my plot but can't find how to do it.
I tried to tune mar but it enable more room for the labels to be displayed
but it does not move to ylab as I would like.
Is there a way with par to shift down my ylab ??
Cheers

No in fact this is not working as all main,xlab,ylab are shited if mgp is
changed
Any help ?

thanks Phillip for the trick.
However I am a bit surprised that something as trivial as this is not
accessible via par options...
If somebody know how to do it with par ... or anything from graphics would
be nice to know

Hello everybody,
I have a list.array which is a list containing arrays, lets say
list.array= list( c(1,2,3),c(5,6,7),c(1,4,6,7,8) );
I would like to apply the union function to those 3 vectors to get the union
of the three : [1,2,3,4,5,6,7,8]
I tried do.call(what=union,args=list.array) but this
Thank you very much, this solve the problem, but more generally is there a
function that allow to apply a function to a list of object, applying
recursively the function to each answer...
mathematically for a 2 argument function f(u,v) you would like a function g
doing
g(u1,u2,u3,u4,u5)
Yes
Thank you very much, NICE ONE.
Do you have some interesting references about R (I do know some common books
but may be you have some nice hidden books I have never heard about...

Hi all, I am having difficulties to understand how R sort strings:
If I do
R) sort(c(X.,X0B))
[1] X. X0B
So for me, as far as lexicographic order is concerned I can add whatever to
the end, the order will remain the same, but :
R) sort(c(X.Z,X0B.Z))
[1] X0B.Z X.Z
Can somebody give me a trick
Ok so it changed from 2.12.2 to 2.14.1 ??
Can somebody tell me how to modify my sort or whatever to get the save
resilt that I would get in 2.14.1 ?
Cheers

ok I was thinking that R would handle the split by itself.
I guess using eval we can even make arg1=val1 being executed by R.

More specifically.
I know that a condition for a VAR(p) process to be stable (weakly
stationary) is that the companion form of the equation (see AWESOME Pfaff
book analysis of integrated and cointegrated time series in R) as
eigenvalues of modulus 1.
My problem is that I want to generate such

Thanks for the answer but my point is not how to simulate a VAR(p) process

My question is more how can I generate a VAR(p) such that I already know
that it is stable.
