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 (

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

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

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?

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.

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

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

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..

But how do I analyze the frequencies correctly?
