p-values for ARIMA coefficients
Hi,
I'm a beginner using R and I'm modeling a time series with ARIMA.
I'm looking for a way to determine the p-values of the coefficients of my model.
Does ARIMA function return these values? or is there a way to determine them easily?
Thanks for your answer

plot question
Hi!
I want to display 2 graphs with different number of data points on the
x-axis. The code below scales them so it seems that testtwo has the
same number of data points as testone. How can I fix that? thanks.
z<-1:50;
x<-1:100;
plot(x,testone,type="l",xlab="",ylab="",main="",lty=4,axes=FALSE,ylim=c(-1.0,1.0),cex=1);
par(new=TRUE);

error bars in line plots
Hi!
Could you tell me how I can draw a graph with error bars?
Sorry, I don't use R that often and I couldn't find it easily in the
documentation.
TIA

Myriam Saavedra M. Sc. Questions about maximun radius distance
Dear Mr. Baddeley
I just graduated from a Masters in Applied Mathematics on Jun19th. My thesis was about spatial distribution /a nalysis of some trees in a part of the Congo Basic Forest.
In my thesis I used your spatial package in R, and today I'm doing a more deeper study about how we choise the r distance in Function F(). I would like to
be able to understand about value of rmaxdefault

easy graphic question
Hi!
How do I specify a filled point in a scatterplot? Their size?
plot(x,y) just gives "empty" points like "o". I want a full black
point.

stats::decompose - Problem finding seasonal component without trend
Hi R-help,
I'd like to extract the seasonal component of a short timeseries, and was
hoping to use stats::decompose. I don't want to decompose the 'trend'
component so I thought I should call decompose(x,filter=0). I think I've
either misunderstood the filter argument or come upon a bug/feature in
decompose.

read.table conversion question
Hi!
I would like to read data read with read.table row by row into a
c() vector.
data<-read.table("test",header=FALSE)
for (i in 1:length(data[[1]])) {
temp <- ??
do something with temp
}
data[1,] gives me
V1 V2 V3 V4 V5
1 1 -1 -1 -1 0.33
c[temp[1],temp[2]) gives me
$V1
[1] 1
$V2
[1] -1
Sorry if that's well known but I can't still figure it

problems downloading R-1.6.1
Hi!
There is a "musical" note next to the rpm in CRAN and its mirrors and
it seems to require some sort of plugin that I don't have. Is there a
way around that?

ts; decompose; plot and title
Is there any way to give a "decent" title after I plot something
generated by decompose?
For example:
# generate something with period 12
x <- rnorm(600) + sin(2 * pi * (1:600) / 12)
# transform to a monthy time series
y <- ts(x, frequency=12, start=c(1950,1))
# decompose
z <- decompose(y)
# plot
plot(z)
Now, the title is the ugly "Decomposition of additive time

igraph: decompose.graph: Error: protect(): protection stack overflow
I just got this error:
> library(igraph)
> comp <- decompose.graph(gr)
Error: protect(): protection stack overflow
Error: protect(): protection stack overflow
>
what can I do?
the digraph is, indeed, large (300,000 vertexes), but there are very
many very small components (which I would rather not discard).
PS. the doc for decompose.graph does not say which mode is the default.

regarding changing of title of decompose graph
Hi All,
I am new to this forum. I have just started learning R. When i use
plot(decompose(x)), i am getting the title " Additive time series
decomposition". How to make this title off and change to some other title.
Any help regarding this is highly appreciated.
With sincerer regards,

Help with STL function to decompose
Hi everyone.
I'm having some troubles with STL function to decompose some data.
My issue is that I have monthly data from September 2005 up to August 2010
i. e. 60 observations.
I define it in the following way:
*u<-read.csv("C:/CELEBREX.csv",header = TRUE)
u.ts<-ts(u, start=c(2005,9), frequency=12)

The issue is that when I try to use

split/decompose lines
Dear R users,
I have a very simple problem but I can't find the function in R to deal with
it.
I need to split (or decompose) one line into many lines using one field as a
reference.
I have a table with the following format:
A B Frequency
23 3 2
24 2 5
25 1 3
And need to split each line into several lines according to the frequency to
achieve something like this:

decompose a correlation matrix
Is there a simple way to decompose the upper triangle
of a correlation matrix to a linear list;
For example:
X Y Z
X 1 2 3
Y 2 1 4
Z 3 4 1
so you get a list like:
xy 2
XZ 3
YZ 4
I suspect you can do it with a matrix transformation, but
that beyond me at present.
Many thanks
Mark
