problem with pdf() on Mac Os X
Hello R helpers,
I am quite new as a R user, and even more on a Mac Os. I am running R
under Emacs 21.3.30.5 through ESS.
I have some problems with the pdf() device : when sent to it, plots
don't come out with any
labels, titles or whatever written. I don't have that problem when
plots are sent to X11 or postscript devices.
As pdf is the native format on Mac Os X, i find it sad to

Sound deformation during conversation or IVR message
Hi,
We have a working asterisk with 1 E1 and a TE405P.
During conversation, when one side is speaking, the other hears sometimes
(every 5 to 20 seconds, it is random) a little deformation of the
voice/sound. It sounds like "scricth" and not during more than 0.5 seconds.
We have exactly the same problem when asterisk give messages to caller by an
IVR.

Draw overlap ellipse in R
Dear list,
I am trying to plot 4 overlapping ellipse showing the overlap among 4 data
sets. Could any one suggest how to make this plot with R?
Thanks!

QQplot
Hi!
<http://r.789695.n4.nabble.com/file/n4651293/qq.png>
We are stuck with a problem considering the qqplot of a dataset.
We are trying to discover what kind of distribution this is. We already
tried to normal, exponential or the logaritmical distribution but none of
those are able to solve our problem. Is there someone able to tell us what
kind deformation we should try?

DataEllipse versus Ellipse Function in R
Hi:
Does Ellipse and dataellipse function in R produce the same ellipse? I
wanted to see how the radius for the Ellipse function in R calculated. Also
what is the var-covariance matrix, if any, assumed for the dataellipse
function? Heres an example of the code where I am generating Multivariate
normal data and creating ellipse using the 2 functions:

Observation in a confidence ellipse
Hello everyone
I really need some help here. I made a confidence ellipse using the function ellipse from the package ellipse:
ellipse(SD, centre=colMeans(pcsref),t=sqrt((p * (n-1)/(n-p))*qf(0.99, p,n-p))
Now, I want to write a function whom return TRUE or FALSE if a given observation is in the confidence ellipse. But I have no clue how to do it
Can anyone help me?
Best regards

the graph gallery strikes back
Hello useRs and helpRs,
Some time ago, in a gallaxy far away (here is the thread :
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/46532.html ) we
discussed about a graph gallery showing the power of R in that domain. I
did some work around that, and there is a (pretty advanced) draft here :

ploting an ellipse keeps giving errors
library (ellipse)
shape1 = c (1, 0, 0,1)
dim(shape1) = c(2,2)
ellipse (center = c(0,0), shape = shape1, radius = 1)
=============================
Error in plot.xy(xy.coords(x, y), type = type, col = col, lty = lty, ...) :
plot.new has not been called yet
It is really frustrating. Also what do the shape matrix, radius correspond to an ellipse function
(x-x0)^2/a + (y-y0)^2/b = 1
?

Is a point into an ellipse
Hi,
I drew an ellipse with the package ellipse. Now I would like to know if
a point is inside the ellipse. Is any R functions to do it without
computing the equation of the ellipse manually? Thanks.
For example, if I do "plot(ellipse(0.8), type = 'l')", I would like to
know if (0,1) belongs to the drawn ellipse.
Regards,
Alain

adding an ellipse to a PCA plot
Hi,
I created a principal component plot using the first two principal
components. I used the function princomp() to calculate the scores.
now, I would like to superimpose an ellipse representing the center
and the 95% confidence interval of a series of points in my plot (as
to illustrate the grouping of my samples).
I looked at the ellipse() function in the ellipse package but can't
get it

Ellipse that Contains 95% of the Observed Data
I can take the results of a simulation with one random variable and generate
an empirical interval that contains 95% of the observations, e.g.,
x <- rnorm(10000)
quantile(x,probs=c(0.025,0.975))
Is there an R function that can take the results from two random variables
and generate an empirical ellipse that contains 95% of the observations,
e.g.,
x <- rnorm(10000)
y <- rnorm(10000)
?

Confidence ellipse for correlation
Hello,
SAS' point and click interface has the option of produce a scatterplot with a
superimposed confidence ellipse for the correlation coefficient. Since I
generally like R so much better, I would like to reproduce this in R. I've
been playing with the ellipse package. In order to have the points and the
ellipse on the same graph I've done the following.

confidence / prediction ellipse
Hi,
I'm using the R library(car) to draw confidence/prediction ellipses in a
scatterplot.
>From what i understood the ellipse() function return an ellipse based
parameters: shape, center, radius .
If i read dataEllipse() function i can see how these parameters are
calculated for a confidence ellipse.

SIP Trunking Mantra (Origination)
Hello Everyone,
We are currently having talks with various service providers, and
trying to determine what the best way is to interconnect in order to
have access to the PSTN network. As you know there are two ways of
doing this:
Traditional PRI: Have trunks grouped into a transport layer such as
OC3/12. With DIDs attached to the group. As you many know, this
approach would also require a POP

Plotting an ellipse in 3D
I have been using the ellipse function from the car package and the
covariance matrix to draw an ellipse around a group of points to show the
confidence limits. However, the points are actually represented by 3
variables so rather than plot each pairwise combination of variables in 2D I
would like to plot the 'ellipse' in 3D using the djmrgl package. Can anyone
offer advice on how I can

Adding axis to an ellipse: "ellipse" package
Dear list members,
This might be a silly question but I just can't figure it out. I am using
the "ellipse" package on covariance matrices. I would simply like to plot my
ellipses WITH its two axis ploted as well. These axis represents the 2 eigen
vectors of my matrix and it is important that I can graphically show them.
Is there an easy way to do so?
Many thanks,

ellipse -confidence interval
Hi!, I made a plot with two variables representing the first two axis of a
principle component analysis. My question is:
How can I superimpose on such plot an ellipse that represent the 95% interval of
confidence of scores?
