Hi, I have a samba server configured with SECURITY=USER and am having trouble getting the UNIX PASSWORD SYNC to work. When I use smbpasswd to change a samba user password, everything goes well and the samba password is changed but the unix password is not changed. Per the manuals, samba trys to change the unix password first and if it fails, it will NOT change the samba password. However, the

I have tried to encode a ridit function. (cf. Bross IDJ: How to use ridit analyses. In: Biometrics 1958(14): 18-38. Application e.g.: Goossen WTF. Exploiting the Nursing Minimum Data Set for the Netherlands. In: Medinfo 2001 2001: 1334-1338. http://cmbi.bjmu.edu.cn/2001/medinfo_2001/Papers/Ch16/Goossen.pdf.) Questions and hints: - Is there already a ridit function in R? - Argument ``b.sel.attrs'' could be omitted. - Perhaps there are more efficient ways than calculating: viq.ridit <- apply( t( t(x) * vjq.ridit.attr ), 1, sum, na.rm=T ) / apply( x, 1, sum, na.rm=T ) -...

I've written a package to assist with using R in Hadoop Streaming. The main point of the package is to help make command-line runnable RScript files. I'd like to provide a demo RScript file, a demo data file (e.g. a plaintext file, not something already processed by R) , as well as demo bash shell scripts that demonstrate how to run the job from the command line and in a Hadoop

I am trying to fit a normal linear model with response y and predictor x and two factors sex and group. I would like each combination of sex and group to have individual slopes and then subsequently have parallel slopes. I tried the model y ~ x*sex*group and it seemed to work for the first case.. Is this how it is supposed to be done? For the second the model y ~ sex + group seems to work. In

Hi, I just get a question (sorry if it is a dumb one) and I "phase" my question in the following R codes: group1<-rnorm(n=50, mean=0, sd=1) group2<-rnorm(n=20, mean=1, sd=1.5) group3<-c(group1,group2) Now, if I am given a dataset from group3, what method (discriminant analysis, clustering, maybe) is the best to cluster them by using R. The known info includes: 2 clusters,

Hello! In the book Modern Applied Statistics with S (4th ed), section 5.6 the concept of the "average shifted histogram" or ASH is mentionend. Also it is mentioned in the same section "The code used is in the scripts for this chapter" (from figure caption 5.8, analysis of the geyser duration data). *However*, I have trouble finding the code for that function! Admittedly, I am a

I've got a server running CentOS 5.2 and has a working NFSv4 server. I've been looking for some help on this on the net, but haven't come across anything that looks like it would pertain to my situation. Basically, I've got a mixed distro environment (CentOS, Fedora, openSuSE, Ubuntu, Puppy, and yikes possibly a Windows box) on various desktops and laptops that I want to connect

Dear list, Can anyone provide a package or code for estimating the parameters of a mixture of c (c >=2) univariate normal distributions? I've tried the algorithm provided by Venables & Ripley (1999) p 263, for the mixture of two normal, but I don't find the "ms" function in R. I've used nls instead, but I'm not sure if it works the same. The data I have is very
