CentOS 7 "compose" process
I am looking for documentation on the CentOS 7 "compose" process,
specifically, the tools and scripts that generate the LiveOS
image contained on the DVDs, as well as whatever produces the
final DVD iso image files (mkisofs + isohybrid + ???).
I asked on the -devel list, and the suggestion was to use this
list instead.
As far as I can determine, Fedora does this via pungi, but I

Ploting a function of two arguments
Hi,
I've written a function:
myfun <- function(x, y) {
// blah blah
}
and I want to graph it. My plan is to use persp(), and my question is:
how do I create the array of values? One possibility is:
x <- seq(0, 10, by=.1)
y <- seq(0, 10, by=.1)
inputs <- <somehow create an array of x,y pairs>
outputs <- apply(A, c(1,2), myfun)
The "inputs" array would

Need help ploting time series
Hi:
I been having a lot of trouble trying to plot multiple time series on the

I have a table with sales per day on different states and what i would like
to do is plot time series for all the diferents states in the same plot
(divided in small squares, not all the time series together) so I can

heatmap and phylogram / dendogram ploting problem
Hi,
I have trouble with the heatmap function (package stats). The row labels
are wrongly ordered and don't correspond to the Rowv dendrogram. I know
there is a bug with the heatmap fonction. Emmanuel Paradis
(http://tolstoy.newcastle.edu.au/R/e2/help/07/05/16227.html )suggested a
modification to fix it but in my case the row labels are still wrongly
ordered.
Heatmaps with 2 phylograms have

Please help!! How do I set graphical parameters for ploting ctree()
I'm trying to understand how to set graphical parameters for trees created with the party package. For example take the following code:

airq <- subset(airquality, !is.na(Ozone))
airct <- ctree(Ozone ~ ., data = airq,
controls = ctree_control(maxsurrogate = 3))

My problem is, I've got a ctree that has

Ploting 3D cylinder in RGL
Dear all,
I would like to draw a 3-D horizontal cylinder preferably in RGL device
(because this gives the look from different angles). Basic idea is from
http://www.tau.ac.il/cc/pages/docs/sas8/insight/chap18/sect3.htm.
Below is the description exactly what I want to do.
Please see at figure 18.6, 1st plot. Here it is an confidence ellipsoid.

ploting axes plaxes ?
I used in previous versions of R (R 1.1) to plot axes on projections of
factorial coordinates using the function plaxes. This doesn't exist any
more. Why this change ? No alternative ?

Ploting betas and p-values together
Hi all,
I have a data frame consisting of extracted results from a moving
regression. Next, I want to write a function that pick up the desired
coefficient columns and plots them on one page (about=5). Additionaly,
the plots should display the corresponding p-values. As for the
coefficients alone, it works fine. The problems arise when I try to add
the values of p-values as lines.

Histogram ploting
Hi,
It's my first post on this group.
I've just started learning & using R and I like it ;-)
I have I think simple question. I'm trying to plot
a histogram for my data set.
My data set is defined as follows:
Class N
12.5 3
17.5 10
22.5 12
27.5 8
32.5 7
37.5 3
42.5 4
47.5 2
Class means middle of set of my ranges I define.
N column stores number of measurements counted to
