rrp.impute: for what sizes does it work?
Hi,
I have a survey dataset of about 20000 observations
where for 2 factor variables I have about 200 missing
values each. I want to impute these using 10 possibly
explanatory variables which are a mixture of integers
and factors.
Since I was quite intrigued by the concept of rrp I
wanted to use it but it takes ages and terminates with
an error. First time it stopped complaining about too

Text data
i have a data column of text entries:
26M_AN_C.bmp
22M_AN_C.bmp
20M_HA_O.bmp

26M_HA_O.bmp
22M_HA_O.bmp
31M_AN_C.bmp
38M_HA_O.bmp

And I would like to sort by the middle tag: AN, HA, etc.
Is there a way to parse text data in R?
In excel, I would have used the "left" and "right" function to cut out just
the middle two letters out and put into another

Segfaults when playing GSM files
My Asterisk has started *frequently* segfaulting during IVR and voicemail
activity -- it'll be playing a prompt gsm file to a caller and it'll just die
(segfaulting, naturally dropping the caller) with no rhyme or reason.
I've run gdb on four different core files and each one shows the reason for
the segfault to be the following:

trouble with cloud output to bmp when in loop
I have some data that I need to view in various 3-D clouds. To better see
the cloud structure on a 2-D screen I would like to output a bunch of bmp
files with clouds at slightly different angles, then run them through an
external program to animate them. But I'm having trouble getting cloud()
from the lattice package to output to bmp files. Oddly, this is only a
problem when outputting

Patch to fix ArtProvider and ArtProvider sample
These patches better implement ArtProvider and add the demo for it. I
also expanded the bigdemo window a little bit. I really think we should
go larger but I suppose there might be some people at 800x600 still.
Note that creating your own art provider still doesn''t quite work
correctly. I didn''t have time to get into that.
The RubyConstants.i.patch file looks weird. Not

no transparent background in bmp
I've been attempting to export a graphics file of my lattice plots and no

PPM to BMP converter
Dear all,
Several days ago, I posted How to write a bmp file pixel by pixel. Instead of bmp, I succeeded in writing a PPM file by using the pixmap package. Thanks for the hint generously provided by Uwe Ligges.
Now I have a new question. How to convert a PPM file to BMP file in R? I know I can do this in photoshop or by some other softwares, but I think if I Can do this in R, that

Beginner graphics device questions.
Please forgive me if this has been asked before but I could not readily find an answer. First, from the example I was able to determine that graphics device commands such as plot can be redirected using 'png' and 'bmp' type commands. I tried this and it works as I understand it. The question is how this graphics device works. If I issue another 'plot' command will it also

bmp() shifts the image (Windows XP)
When using bmp() under Windows XP, I find that the saved image is a
shifted version of the correct image. Try this:

stat(2) cache, samba3 versus samba4
Short version:
Is there a way to enforce use of this cache:
./source3/smbd/statcache.c
I noticed it is absent from the ./source4 directory
I limited
server max protocol = SMB2
but that didn't do it.
Long story:

My samba server (4.2.14) hosts a couple of game install trees for a
Windows 7 computer.
Some of the games cause storms of stat(2) system calls, here is a

file.copy() problems on WinNT (PR#1085)
For some files, file.copy() doesn't copy these files correctly.
Here you will find a file (Bitmap, 769Kb) to reproduce the problem:
http://www.statistik.uni-dortmund.de/leute/ligges/R/test1.bmp
Using
file.copy("c:/test1.bmp", "c:/test2.bmp", overwrite = TRUE)
produces a second file with the size of ~1.4 Mb:

Strange behavior of savePlot
Hi all,
I am using savePlot in a loop for saving several graph but I get some
graph in 553x552, some other in 1920x1119. How comes ?
My data are almost all the same (same label, same xlim / ylim, almost
same data. Only the color changes). I save them in bmp.
Thanks for your help.

X11 & dev2bitmap
Hi,
I am trying to put some graphics I have generated from R on a
webpage using dev2bitmap to create a bitmap, .BMP, file.
When I look at my notes from 2 or 3 months ago I was successfully able to
put the ACTIVE device plot result into a bitmap file using a command such
as:

Job done!
Now when I try the same command, I get the following:

Polycom IP 500 bitmaps and Idle Display Animation
Has anyone got this to work? Under Idle Display Animation, the

In the ipmid.cfg file, I enabled 'ind.idleDisplay.enabled' (ie changed
it to 1), and under the IP 500 section, I added an entry for the bitmap

ferret using UTF-8
Hey all,
I went through the docs in Ferret''s page, plus a quick search through
the email list (thread titles), and I couldn''t find any info on how to
have Ferret storing it''s data using UTF-8.
In the scenario I would use it, nothing''s being stored outside (like
external databases). So it''s just how Ferret would do it that I''m
interesting in
