Hallo! I have data of the following design: NSubj were measured at Baseline (visit 1) and at 3 following time points (visit 2, visit 3, visit 4). There is or is not a treatment. Most interesting is the question if there is a difference in treatment between the results of visit 4 and baseline. (The other time points are also of interest.) The level of significance is alpha=0.0179 (because of an

Hello, i just ran into the following problem: I wanted to recursively solve equations of the type x_1[t]=x_1[t+1]+beta*x_2[t], and used a for-loop written for(j in c(1:t-1, recursive=TRUE){ ... } This didn't work, so i resolved to writing for(j in c(10,9,...,1){ which worked, but is not terribly efficient. So, what did I do wrong? Thanks in advance, Owe -- Owe Jessen Diplom-Volkswirt

Hii, Can anybody help me, I don't know how to print the "median".

Hello together, we try to setup a samba domain controller with LDAP and roaming profiles for Win7-Clients. Everything looks fine last Friday but today the clients did not longer save changes to the profiles. There is no error in samba log and also no in the windows log. If I delete a profile from a client it is loaded correctly at next logon, but the changes are not saved at logout. Windows XP

Hi, we have a debian etch system running here and it works fine for hvms (winxp) and paras (debian etchs). Today i tried to do a SLES10SP2 setup as hvm (in the future it should run as para). I used this config: --------------- xenserver:/etc/xen# cat gp2backuptest.cfg kernel = ''/usr/lib/xen-default/boot/hvmloader'' builder = ''hvm''

Hello! Is there someone already working on an implementation of Splus' chull() function for R? If not, I would like volunteer to try it. For my "Diplom" I implemented convex peeling in C (some time ago), using an O(n log(n)) algorithm, so it probably will prove relatively easy to use that code for a R-function. Well, as least as easy as any programming tends to be. :-) Detlef

Hi, when I try installing new packages (in this case DBI) I run into the following problem: Paket 'DBI' erfolgreich ausgepackt und MD5 Summen abgeglichen Warnung: kann tempor?re Installation 'C:\Programme\R\R-2.7.0\library\file5f906952\DBI' nicht nach '? xlD?? $@\R\R-2.7.0\libra' verschieben Has anybody any idea where these strange symbols come from? Thanks in

Hello, maybe this info is helpful for someone else, at least it is a reminder for me if the problem should reoccur: The last hours R drove me nuts because it wouldn't install new packages, or more irritating still: It would chose randomly which packages to install when given a list ("unable to move temporary installation" ). The solution was to turn of the indexation of

Hi all, this should be a simple question, but I haven't been able to do it right. I am trying to download multiple stock quotes in a loop, so that every timeseries is safed with the symbol of the stock. Can anybody help me out? Here's the code: require(tseries) startd <- "2000-06-01" stocks <- c("bmw.de", "vow.de", "dte.de") for(stock in

AFAIK, all LLVM projects have dependency on the configure project but this is only so that some include files are created, no

Hi, I got the following problem. I am doing a maximum likelihood estimation for a Kalman Filter. For this purpose, I have to invert an error matrix Ffast of dimension "no. parameters X no.parameters". The usualy optim methods often find only local minima, so I decided to make the optimization using the SANN algorithm, which is very slow already. However, this becomes a real problem

Hi I've decided to use xapian because my files table in my mysql database is going to grow very large, and it seems mysql isn't good at full text searching. I'm doing this with the php wrapper by the way. The way my system is set out, each user has their own set of files, and when doing a search it is going to be for a specific user's file (based on file name, title,
