the "union" of several data frame rows
Hi,
I have a question about how to obtain the union of several data frame
rows. I'm trying to create a common key for several tests composed of
different items. Here is a small scale version of the problem. These
are keys for 4 different tests, not all mutually exclusive:
id q1 q2 q3 q4 q5 q6
1 A C
2 B D
3 A D B
4 C D B D

graphics backgrounds from gray to white in png()
Hi,
I'm trying to make a png file of a histogram. I would like a white
background in the final product but end up producing a gray one, despite
setting what I think are the correct parameters. Suggestions for how to
properly set a white background would be welcome.
Thanks in advance,
Scot

Correlation ratio
Hi,
I wanted to know how to compute the correlation ratio (eta) between two
variables using R. Is there any function to compute the correlation ratio.
Any help will be very much appreciated.
Thanks,

[PATCH] Enable PCI passthrough with stub domain.
This patch enables PCI passthrough with stub domain.
PCI passthrough with stub domain has failed in the past.
The primary reason is that hypercalls from qemu in stub domain are rejected.
This patch allows qemu in stub domain to call the hypercalls which is
needed for PCI passthrough. For security, if target domain of
hypercall is different from that of stub domain, it rejects hypercall.

Help on programming
I am a new user of R and would like a bit of advice.
I wish to write a short program in R that I can call up when I want to run
it. How do I go about storing and recalling the particular code that I
write?
Many thanks
Bob Banks

Part II Re: read.ssd {foreign} (Reading a permanent SAS d ataset into an R data frame)
Scot,
Thanks for the info. I will try your code out to
verify the result, but before I do that, will your
code (SAS and R) work with variable names that are
longer than 8 characters long without truncating the
variable name in R?
Also, I wonder about using your method or the PROC
EXPORT method with larger data sets. The data sets I
will be working with for the most part will not be
that large,

Labeling matrix data
Hello all -
I am sorry if this simple question is addressed in somewhere else. But, I couldn't find it. It's been for about a week using R. . .
My problem is:
Reading matrix data with "scan" does not seem to allow me to incorporate matrix labels (columns, and rows).
If I use read.table, I can import the lables. But, the problem is, I don't know how I make this data as

missing ctest and methodological question
Hi,
I couldn't figure out how to use the functions from the
ctest library. I'm using the r-base package that comes with
debian potato. library("ctest") told me that no such package
existed. I checked the CRAN, but no such package was
availiable, instead I was told that it would be part of the
standard installation. But functions from ctest like
shapiro-wilk don't work. The

Part II Re: read.ssd {foreign} (Reading a permanent SAS d ataset into an R data frame)
Scot,
Thanks for the additional information. On further
reflection... whether one uses SAS PROC EXPORT or uses
a SAS LIBNAME yourfile XPORT 'yourpathname';
statement, an intermediate file is created in either
case. As far as experience tells me now, PROC EXPORT
is a far superior choice, because variable names do
not get truncated and you only have to deal with

small first graph of par(3,2), other 5 are correct

I'm trying to produce 6 graphs on a single page using code I've borrowed
from an example by Paul Murrell:

It involves placing 6 horizontal barplots on one page and adding common

The problem is the first graph in my figure (the one in the (1,1)

Openbugs and rbugs on mac with wine
Hello list,
I?ve been trying to get OpenBUGS running on my mac using the wine
emulator. I can run Openbugs just fine by doing:

In the terminal, so OpenBUGS works. When I try to run the schools
example using rbugs(), the OpenBUGS process starts in wine, but it
just sits there, no log, no script, no output of any sort. The rbugs

A question about bugs.R: functions for running WinBUGs from R
Dear R users,
I've found bugs.R : the functions for running WinBUGs from R that is
writen by Dr. Andrew Gelman who is a professor from Columbia University.
The bugs.R would be very useful for me, and I think many of you know it
as well. I followed the instuctions on Dr. Gelman's web to install all
of documents that bugs.R needs, but when I try to run the school example
