effects in ANCOVA
Dear R users,
I am trying to fit the following ANCOVA model in R2.4.0

Particularly I am interested in obtaining estimates for mu, and the effects

Sweave doesn't do csv.get()
Hi Everybody
I use R2.8.0 on Mac OS X. I set up LyX 1.6.1 to use Sweave today. I can
compile the test file I found on CRAN (
http://cran.r-project.org/contrib/extra/lyx/) without a problem and the
output looks very nice. In the test file the following R code is used.
<<myFirstChunkInLyX>>=
xObs <- 100; xMean <- 10; xVar <- 9
x <- rnorm(n=xObs, mean=xMean, sd=sqrt(xVar))

returning value from source() in R .Net
Hello
I would like to source an R script from within a C# .Net application equivalent to:
source("my_r_code.r")
I can get this to run but am not sure how to retrieve R objects defined with script my_r_code.r at runtime.
For example, if "my_r_code.r" contains
#-- contents of my_r_code.r---------------------
x <- 1:10
xmean <- mean(x)

Generic code for simulating from a distribution.
Hello all,
I have the code below to simulate samples of certain size from a
particular distribution (here,beta distribution) and compute some
statistics for the samples.

{
sim<-matrix(rbeta(nsim*n,alpha,beta),ncol=n)
xmean<-apply(sim,1,mean)
xvar<-apply(sim,1,var)

tabulate means & NA
Hi,
i have some problems to get means, but the data have got
NA's which should not be replaced or delete !
tapply(data,var,mean) # makes me problem,because when one value is
NA mean is NA,too.
Another attempt is this, because the summary does what i want , but
is not subsetable to summary[4] if i use tapply,table and the the
function below gives me
again all means as NA ?

help annotating plot.xmean.ordinaly in rms package
Hello List:
Does anyone know if there's a way to annotate the plots produced by the
plot.xmean.ordinaly function in the rms package. I'd like to produce
publication quality figures, but first need to annotate the axis labels. Is
there a way to do that?
I appreciate any advice.

Trying to use segmented in a function
Hi folks
I wonder if anyone can help me. I want to run some simulations to see
how big a sample size might be necessary to distinguish a curved
bivariate relationship (e.g. something that might be best described
by a quadratic model) from a relationship that is two straight lines
with a sudden change in slope (e.g. something best described by a
breakpoint regression). I am using

correct way to subset a vector
Hi,
#make example data
dat <- data.frame(matrix(rnorm(15),ncol=5))
colnames(dat) <- c("ab","cd","ef","gh","ij")
If I want to get a subset of the data for the middle 3 columns, and I
know the names of the start column and the end column, I can do this:
mysub <- subset(dat,select=c(cd:gh))
If I wanted to do this just on the column names,

NAMESPACE and imports
I am cleaning up the rms package to not export functions not to be called
directly by users. rms uses generic functions defined in other packages.
For example there is a latex method in the Hmisc package, and rms has a
latex method for objects of class "anova.rms" so there are anova.rms and
latex.anova.rms functions in rms. I use:

Hello Thomas and Karl, thank you for your answer and time.
We've tested with several listeners and different connections, using
WinAmp and JW Player. For about 15 minutes, everything is ok. After
15-18 minutes, WinAmp starts do blink that "red square" (packet loss or

Coding problem: How can I extract substring of function call within the function
In order to ease my students into the R environment I am developing a package which installs a variety of utility functions as well as slightly modified versions of some standard R functions -- e.g. mean, hist, barplot, .... In my versions of these standard R functions I either add options or alter some defaults that seem to create difficulties for most of my students -- for example, when they do

Intrusion Detection
Hello all,
I have been exploring the various intrusion detection systems available for the Linux platform and was wondering what ones you all would recommend? I have used AIDE before and while it is extremely easy to setup, it does not support the ability to send alerts as files are changed (allows one to be aware of an intrusion almost immediately).
Thank you,
