What library is coxreg?
Dear mailing list,
I'm trying to run the sample program about coxreg in the eha package. But the
command is not recognized. I tried the boot and also the survival library.
Hope you can help me solve this little problem.
Thank you.

efficient R code
Last Friday, Gregory Chaitin (http://www.umcs.maine.edu/~chaitin/lm.html)
mentioned that there can be no proof that a given code is the shortest for
a problem, even within a language. Still, the script below, a replacement
of the "TDT", one of the most frequently used tests in genetics
(http://mustat.rockefeller.edu under "downloads") may get close. It

Help with apply
Suppose I have the following data:
tmp <- data.frame(var1 = sample(c(0:10), 3, replace = TRUE), var2 = sample(c(0:10), 3, replace = TRUE), var3 = sample(c(0:10), 3, replace = TRUE))
I can run the following double loop and yield what I want in the end (rr1) as:
library(statmod)
Q <- 2
b <- runif(3)
qq <- gauss.quad.prob(Q, dist = 'normal', mu = 0, sigma=1)

QQ International -- Almost works, but always says I'm "Away"
I got QQ International (version 1.0) to work via WINE under Mepis 8.5. Using winetricks, I installed all of the missing DLL's, and QQ now starts up and runs fine.
... except for the fact that it always shows me as being "Away". Even if I manually set my status to "Online", it changes me back to "Away" after a second or two.
This only happens under WINE. I log in

mixed formatting of integer and numeric (e. g., by summary.default())
Hello, eveRybody,
I've been trying to find the origin for the following
formatting-"inconsistency":
E. g., look at the number of digits in summary.defaults()'s output when
NAs occur: in my example below the number of NA's is displayed as an
integer, the rest as numeric (floating point numbers):
> summary.default( c( 1:2, NA))
Min. 1st Qu. Median Mean 3rd Qu.

Question on Data Simulation
Dear mailing list,
Do you know a specific package in R where I can create an artificial survival
data with controlled censoring condition? (For example, I want to simulate a
data set with 5 variables and 20% of the observations are censored.)
Many thanks.

QQ plot
Hello,
I am having two data set original and predicted.
I want to dind QQ-plot fot it.
I tried in following manner :
>qq(original~predicted)
and error was :
Error in qq.formula(o ~ p) : y must have exactly 2 levels
There is an option "qtype" which dosent make any difference.
What is the correct way for plotting QQ-plot or am I missing something.

Generating R plots through Perl
Hello,
I am in the process of writing a Perl program to carry out and analyze
large numbers of regressions using R as the regression engine, and I am
using Statistics::R to create the communication bridge between the two
programs. Statistics::R creates a pipe between R and Perl and uses
Rterm.exe (hidden during run-time) to carry out the R commands. This
communication bridge works well for

Internal error in 'ls' for pathological environments (PR#14035)
nchar(with(list(2),ls())) gives an internal error. This is of course
a peculiar call (no names in the list), but the error is not caught
cleanly.
It is not clear from the documentation whether with(list(2)...) is
allowable; if it is not, it should presumably give an error. If it is, then
ls
shouldn't have problems with the resulting environment.

Dears,
My samba version is 3.6.4
I have a problem to co-work with open LDAP server. When samba join to open LDAP server, my local account can NOT login samba anymore, only LDAP account can login.
When my samba come back to standalone, the local account is OK. Did I miss something?

once more: methods on missing data
Thanks for replies, but i was not precise enough.
The problem is not evaluating statistics on data with NA values.
The problem is evaluation of statistics on data with length = 0.
To make the problem more clear this is what i tried:
This works fine:
tapply(as.numeric(c(NA,2)), as.factor(c("a","b")), summary)
But i need SDev, aswell, so i copied summary.default to

a very easy question, how to extract the name of the response variable
This may not be the smoothest way to produce the result, but here is a
two-step solution:
first find the formula within the object created by the call to glm():
form <- qq["formula"] or equivalently form <- qq$formula
then apply the function all.vars() to the result, and return the first
element
variables.in.formula <- all.vars(form)

[LLVMdev] HELP: Clang options needed in command to compile device driver into linux module.
BTW, the Makefile is as folllow,
CC := gcc

confused by switch() and the letter E
I can't get switch() to work as expected with the letter 'E'. The following example from help works just fine.
> ccc <- c("b","QQ","a","A","bb")
> for(ch in ccc) cat(ch,":",switch(ch, a=1, b=2:3), "\n")
b : 2 3
QQ :
a : 1
A :
bb :
Now I replace "a=1" with "E=1"

(-1 as index) OR (envelope for QQ)
I'm new to R (and to S) and am wondering about code from pages 72 and
83 of MASS (Venables+Ripley, 3rd edition), to draw an envelope on a QQ
plot. Copying from the book, I've got:
#... code whose gist is "a.fit <- nls(..."
num.points <- length(resid(a.fit))
qqnorm(residuals(a.fit)) # illustrate data-model residuals
qqline(residuals(a.fit))
