Simulation in R - Part 2
Hello!
So, the simulation works (drawing 100 samples and then calculate the
model for each sample). Here is the code:
--snip--
# sample size n=200
ergebnisse200 <- rep(0, each=100)
stichproben200 <- vector(?list?, 100)
default200 <- rep(0, each=100)
for (i in seq(1:100)) {
n <- dim(daten)[1]
ix <- sample(n,200)
samp_i <- daten[ix,] # draw samples
y <- sum(samp_i$y)

Questions about generating samples in R
Hello!
I have a data set with 8 columns and in about 5000 rows. What I want to
do is to generate samples of this data set.
Samples of a special size, as example 200.
What is the easiest way to do this? No special things are needed, only
the random selection of 200 rows of the data set.
Thanks
Alex

Human readable output
Hello,
I would like to suggest an option to rsync that makes it output sizes
in human readable units, instead of always using bytes. So
Total file size: 30864401502 bytes
would be output as:
Total file size: 28.7 GiB
Similarly for mebibytes and kibibytes.
If there's already such an option, then I'm sorry -- I didn't find it
in the manual pages.

Problems with ks.test()
Hi,
I got two data point vectors. Now I want to make a ks.test(). I you print
both vectors you will see, that they fit pretty fine. Here is a picture:

R plug in for Eclipse
Hello,
Is there any R plug-in available for Eclipse other than StatET?
StatET doesn't seem to work with the latest release of Eclipse properly,
i.e. syntax highlighting isn't enabled for R commands. I already contacted
the author some time ago, but have not yet received a response.
Would also be great if somebody could tell me whether they have the same
problem. I already tried

Grouping columns
*Hi @ all,
I have a question concerning the possibilty of grouping the columns of a
matrix.
R groups the columns alphabetically.
What can I do to group the columns in my specifications?
The script is the following:*

>
> #Quelldatei einlesen
> b<-read.csv2("Z:/int/xyz.csv", header=TRUE)

issue with large number of files
Hi,
I use rsync to syncronize two systems.
There are 2 million + files.
My problem is
1. rsync is very slow (it needs more than 48 hours)
2. rsync needs too much RAM (ca. 750 MByte on each server)
The backup software needs 14 hours including file transfer to the backup
server for full backup.
My configuration:
1. Server Dual-XEON with 2 GB RAM.
2. Server Dual-PIII with 2 GB RAM.
The partition

Hi Edgar,

two way synchronization with rsync?
I have two offices in one city; employees work in both of them (once in
office A, the next or an hour later in office B etc.).
They would like to have the same profile (i.e., if they log off in
office A, they would like to have their documents, Desktop, emails etc.
in the profile in the office B when they arrive there an hour later).
Is it possible with rsync to construct such a "two way

Help me with this Questiions
I would like to understand the capabilities of GNU rsync software /
utility. This is used for syncing file systems / file level data across
two systems. I specifically would like to know its capabilities in
syncing files ?
1) How does it replicate data changes to files ? entire file or only
the incremental blocks?
2) Does it have any block level replication capabilities?
3) Can it

CUnit
Hi!
Which testing-framefork do WINE use?
I have seen, that CUnit for example outputs the result in a nice
html-format:
http://cunit.sourceforge.net/ss_automated.html
Looks similar to the output of GNU Classpath (which trys to rewrite Java):
http://builder.classpath.org/japi/jdk15-generics.html
But GNU Classpath uses JUnit. And WINE is written in C, so in this case
CUnit would be better.

[LLVMdev] IR code generation and JIT execution in a multithread environment
Hi Everyone,
my goal is to create a service with multiple threads, each of them
generating IR code and JIT'ing/executing it in their threads
and some threads will share generated code through a code repository...
1. Is there a guideline/docu out there, which describes serialization of
some LLVM objects,
especially llvm::ExecutionEngine, llvm::ModuleProvider, llvm::Module?

[LLVMdev] IR code generation and JIT execution in a multithread environment
Quick related Q:
Does the global lock of the JIT during code generation prevent
concurrent execution of already JIT-ted code?
Thanks.

Mauchly and Levene
Hallo!
I just started working with R to do the statistical analyses for my diploma thesis.
I got two sets of data.
Both contain repeated measures.
One has only one within-subject factor with four levels.
The other has one within-subject factor with two levels and one between-factor with two levels.
I want to compute a Mauchly test for both sets and a Levene test for the second set.
