Visualization of coefficients
Dear all,
I try to show a subset of coefficients in my presentation. It seems
that a "standard" table is not a good way to go. I found figure 9
(page 9) in this file (
http://www.destatis.de/jetspeed/portal/cms/Sites/destatis/Internet/DE/Content/Wissenschaftsforum/Kolloquien/VisualisierungModellierung__Beitrag,property=file.pdf
) looks pretty good. I wonder if there is any function for

replace elements in a list
Dear all, I have a list like this: l <- list(list(a=1,b=NULL), list(a=2,b=2))
I want to find out the elements with value of NULL and replace them with NA.
The actual case has a very long list, so manually find out and replace
them is not an option.
I can use for loop to do this, but I want to know if there is
vectorized way (or other ways) to do it?
Thanks

Gastman
I've tried the precompiled version of gastman, but it does'n work properly under windows, so I would like
to try to compile it under windows, so maybe it begins to work.
I've tried to compile gastman with mingw, but the db3.1 libraries request the cygwin include files and libraries.
Then I've copied the cygwin's include files and libraries to mingw's directory,

RGtk2:::gdkColorToString throws an error
Dear all,
I try to use RGtk2:::gdkColorToString, but it throws an error:
Error in .RGtkCall("S_gdk_color_to_string", object, PACKAGE = "RGtk2") :
gdk_color_to_string exists only in Gdk >= 2.12.0
I know what it means, but don't know to solve this problem because I
don't know where I can download the referred gdk library. Any
information? Thank you.

Example scripts for R Manual
Hi,
I am wondering if some experienced users would help put the
ready-to-run code of the examples in the manuals. It would help new
users learn R faster by putting all the examples in an ready-to-run R
script file. Can somebody help do so sometime and post the code along
with the pdf manuals?

some QCA questions
Dear Adrian Dusa, others,
I've recently started to learn R in order to use the QCA package because
i think it might offer what other QCA packages don't: possibilities for
quite a few conditions and large n. However, can someone tell me approx.
how much RAM i need to run QCA on set of +/- 400.000 cases and +/- 15
conditions? (or differently: how much time will it take with RAM of a

Urgent - odfWeave produces graphs /images with Read-Error
Dear list,
I have been working on a report with around 60 images in it, and
everything has been fine, until now. I find that the image output that
is produced by odfWeave produces images that are NOT readable by
OpenOffice or NeoOffice. I get empty boxes with Read-Error written in
them. While generating the file using odfWeave, I can see them being
generated on the screen, and they all seem fine.

Removing objects from workspace
Hi all,
I am currently woking with hundreds of objects in workspace and whenever I
invoke ls() to observe the names of the objects, there are too much of
unnecessary variables.
For example, if I only require say 3 or 4 objects from hundreds of objects
in workspace, are there any methods that may do the job?
I have tried rm(-c(x,xx,xxx)), but no luck..

predict.lm with NAs
Hi,
I wanted to use the predict.lm() function to compare the empirical data with the predicted values.
The problem is that I have NAs in my data.
I wanted to cbind my data.frame with the empirical values with the vector I get from predict.lm.
But they don't have the same length because predict.lm just skip NA-predictions.
Is there a way to get a vector with predicted values of the same

On page 39 of this paper [1] by Andrew Lo there is a very interesting
correlation network diagram (sorry I dont have a more convenient link to
the type of diagram I'm talking about). does anyone know of any package in
R that can generate these types of diagrams?
