how to inspect content of save file
Is there a way of listing the variables contained in a file created
with the save() command other than load()ing the file?
I have a couple of rather larger files that I would rather not load ...

Columns, the fileds consists of text) directly in a plot? when I use

trouble with package mva on R 1.4.0
Dear List,
although the library() command tells me that the pcakage "mva" is
installed on my machine, I cannot use its functions or get help() about them.
And, strange enough, I never installed the package manually. Has it
become a part of R-base?
I can't find the package among the package sources on CRAN, so I
can't (re)install it manually. I'm using R 1.4.0.
Can anyone

Unexpected behavior in PBSmapping package
Using R 2.5.1 on Windows XP Professional, and PBSmapping package version

of the R-help community.

I've used the Mathematica to produce 3D graphics, contour plots of a
bivariate normal distribution
Now I want make these graphics in R, but i do not know how.
I would like to:

mixture distributions
Dear List,
I am looking for a possibility to fit a mixture model under R using
maximum likelihood estimation.
Venables and Ripley describe a solution working under S+ (in MASS, 3. ed.,
p. 263) which requires the D system function and deriv3. This solution does not
seem to be portable to R or at least I do not realise how.
Is there anyone who

embed image (png) in postscript (device)
Hi,
I output multiple "grid-package-based" plots to the postscript device.
Because the graphics are complicated and consists of a lot of datapoints
(~200'000) the files become really big. To avoid this big files and to
shorten the creation, I currently print the plots to the png device and
manually combine them into one multipaged pdf document.
My question is, it is possible to do

Hi,
I would like to evaluate a function, with 3 arguments, for instance,
myfunc<-function(a,b,c) { sqrt(a)-exp(b)+4*c
}
How to execute myfunc(x,y,z), for all x, all y and all z, where x,y,z are
vectors?
Thank you very much in advance

Rcpp and mclapply
Dear all,
I have an R script that uses Rcpp, and I have been trying to parallelize
it using mclapply (I tried with the multicore and the parallel library)
Sometimes (not always, interestingly), the CPU use for each core drops,
usually so that the total over all cores reaches 100%, i.e., as fast as if
using just one single core fully. I tried my code directly from within
emacs, and also using a

Intermittently stalling PAM authentication children
Hi,
we encounter a problem using PAM with privsep to manage OPIE
authentication : in some -- not really reproducible -- cases, the
child responsible of PAM authentication stalls and continues to run
even if its parent has been closed. The server is the standard RHEL 4
install, which is a 3.9p1 with backported security patches
As this children account for the 'MaxStartups' limit, new

Datapoints underneath datapoints Problem
Hi there.
I have the following graph:
http://www.nabble.com/file/p10928148/map.jpg
However, some datapoints occur at the same place as other datapoints and are
so layered on top of each other. I would like to know if there is any
possible way in which I could view those datapoints that are layered on top
of each other ...maybe by rotating using latitude to show the datapoints

graphical representation of a correlation between 3 variables (~30 datapoints)
Dear Ms and Mr R,
I am seeking a visually appealing presentation of 3 variables (~30
datapoints) that are correlated and that should to into the same direction.
The objective is to show that they do go in the same direction and what
differences there might be while also giving an idea of the values of the
variables. I had done this with simple bargraphs for 6 datapoints in the
past, but for

How to translate the 2D-density matrix (the output of bkde2D function) into matrix of datapoints' amounts?
It is known that function bkde2D (package "KernSmooth") returns a matrix of
density estimates over the mesh induced by x1 and x2. In Details it is
written that "... heights of the kernel, scaled by the bandwidths, at each
datapoint are summed. This sum, after a normalization, is the corresponding
fhat value in the output".
There are several questions:

Undesired vertical lines in png file output using 'cairo-png'
Hello all,
I'm writing a file to PNG on Windows 7 using 'cairo-png'. I've been using
it without problem for a while, but abruptly I'm getting what look like
unplotted areas. I'm using the cairo-png specifically because it
sucessfully generates a transparent background, whereas 'windows' doesn't.
The actual issue has a lot of code I don't think it's

How do you specify font family in png output; png cross-platform issues
For teaching purposes, I prepared a little R program. I want to give
this to students who can run it and dump out many formats and then
compare their use in LaTeX documents. I do not have too much trouble
with xfig or postscript format, but I've really run into a roadblock
where png files are concerned.
My original problem was that the png device does not accept a family option.

heavy graphs
Dear R community, I am creating large graphs with hundreds of
thousands of datapoints. My usual way for output was pdf, but now I am
getting file sizes of >30Mb that do not open well (or at all) in Adobe. Is
there a way to reduce the resolution or get rid of overlaying datapoints?
Any other idea is also warmly welcome!
Thank you and wishing you a good day!
Georg.
