how to get condition number from lm output
Dear r-help,
I ran
output <- lm(formu, data=mydata)
I want to look at the condition number (to see if the matrix is near singular). How?
Also, I use the function stepAIC from MASS to select models, how can I see the condition numbers in each step?
While I am at it. I find a minor bug:

Y2K compliance of R
Hi, I was thinking to ask the University computing Labs here
to install R and I was told they need a statement that the software (R)
is Y2K compliant. Which I cannot find in CRAN. (in addition to the
licensing info).
Is it a big issue to put such a statement in R? or this has legal implications
that R do not want as a "free" software?
If possible I would like to see the statement on

Problem using pkg "survival"
Hello all.
I've been attempting to utilize the "survival" pkg (
http://cran.r-project.org/web/packages/survival/index.html), while reading
through this guide (http://www.ms.uky.edu/~mai/Rsurv.pdf). I figured working
through the guide would be the best way to go, before attempting my own
data.
I tried to utilize the Kaplain-Meier estimator as shown in the guide:

device png() in batch mode?
Dear helper, I am using linux (redhat) R 1.5.0, in the
batch mode.
The device png() do not seem to be available.
A look at the help says png() is available if I
use --gui option.
Is there a way to get around it?
(to get png("Rplot.png") in batch mode?)
The reason I need batch mode is that I am working to get the Rcgi
to run.
Thanks,

simple questions about R (fwd)
OK, I am forwarding this to the r-help. In the original message
I simply hit reply and I thought I send to ALL r-help list. (apparent not)
also I recieved another piece of mail.....about the RNG in
Splus 4.0 or later indicating it was modified and getting worse.
I only have Splus 3.4 for HP. So I cannot try it.
This makes the idea of using the
pre-generated RN on CDROM more appealing..

functions for high dimensional integral
I need to compute a high dimensional integral. Currently I'm using the
function adapt in R package adapt. But this method is kind of slow to me.
I'm wondering if there are other solutions. Thanks.

what is rw0641sp.zip ?
Hi, everyone, I was downloading the rm0641b.zip etc.
(thanks to Guido Masarotto and Brian Ripley)
I noticed rw0641sp.zip there, which do not seem mentioned
in the News file.
My guess is that it is not a binary file?
Is is a source patch file(?) for compiling on Wintel PC?

One user getting: "Primary group is 0 and contains 0 supplementary groups" on standalone server
Greetings,
We are having some rights issues on Samba 3.6.18 running on Slackware64

bug in the ctest package: binom.test
R 0630 for windows
> library(ctest)

returns a p-value of =< 2.2e-016 and a warning

I think it is the

Parallel Processing Interface for lapply()
In co-operation with Markus Hegland and myself, Zhongwen Ding
has written a package, based partly on Markus Hegland's code,
that provides a parallel processing interface to a remote
multi-processsor system. Pyro (Python Remote Objects) and R
must both be installed, both on the client machine and on the remote
server. The system uses rsync, with an ssh protocol, to handle
file transfer.

Still no joy using "print command" with 3.0.30
Greetings once again,
I am still having trouble with the "print command" option in 3.0.30.
In our computer lab, we force CUPS to print the jobs on hold, using:
print command = lp -H hold -d %p %s
This worked well with the Slackware packages of Samba 3.0.28 and CUPS
1.1.23. When I upgraded Samba to 3.0.30, the jobs were no longer queued
on hold, but printed immediately.

r online
Hi,
I'd like to execute simple commands and functions in R through a
website, is there any service like this somewhere?
I only found http://www.osvisions.com/r-online/ but it does not work
(last update 2003) and the links to releated websites only give errors
(if I calculate 7+3).
Thanks for help & hints,

confidence interval given by prop.test()
Dear R-help,
> prop.test(9, 137, p=0.066)
> prop.test(9, 137, p=0.05)
give two different 95% confidence intervals.
I thought the confidence interval calculation
should be independent of testing calculations (and thus
the null hypothesis)?
Splus 2000 has similar problems but give slightly different
answer.
