Hi R Users, Sorry if its out of topic. I would like to ask you about twin peaks - normal distribution. How R can handle it, any example to explain it in R. Thanks, regards, Unung

Sorry, to solve your question I had tried: data(faithful) kmeans(faithful[c(1:20),1],10) Error: empty cluster: try a better set of initial centers But when I run this a second time it will be ok. It seems, that kmeans has problems to initialize good starting points, because of the random choose of these starting initial points. With kmeans(data,k,centers=c(...) the problem can be solved.

Dear all I apologize for cross-posting, but first it is accepted custom to thank the repliers and give a summary, and second I have still the feeling that this problem might be a general statistical problem and not necessarily related to microarrays only, but I might be wrong. First, I want to thank Robert Gentleman, Mark Kimpel and Mark Reiners for their kind replies. Robert Gentleman kindly

On 16 Apr, Unung Istopo Hartanto asked about using R library 'foreign' to import SPSS Data Entry data files. SPSS Data Entry is an application that allows for the creation of formatted data entry forms (as does EpiInfo, Epidata and CSPro (all free downloads)). As such it creates the usual SPSS data files, but adds forms information, which the 'foreign' package does not know how

Hi, I am a new user of R. I have 2 series of nominal data (2 series of answers for the same question) and I want to calculate the correlation between these 2 series. I've tried to use the correlation function (corr, ...) but all are for numeric data... Does anyone know what function should I use for the nominal data? Thanks a lot, Bianca

Hi, I have written code which enables chroot environments for users.

I read in a CSV file with Data <- read.csv(file="FileName.csv",head=TRUE,sep=",") the file containts strings in the 2nd and 3rd columns and each has about 1000 rows. I need to either loop through the strings there looking for strings that would trigger other logic or remove those rows and put them in another array and loop through them in the new array. I can't seem

I've rolled up R-2.0.0.tar.gz a short while ago. This is a new version with a number of new features. See below for the details. As was the case with R 1.0.0, this new version represents a coming of age more than a radical change to R. We do plan to celebrate the new major version with press releases and such. The release will be available from

The current early-printk support for ARM is rather hard-coded, making it hard to add machines or tweak settings. This series slightly moves some code to gather UART settings in xen/arch/arm/Rules.mk instead of the actual .c files. Also it allows two different machines with different settings to share the same driver, which the last patch exploits to add support the Calxeda Midway hardware. This

Hi, all.... Honestly I'm a newbie in Linux. For a couple days, I've been trying to build my own PDC server. I've got enough manual resource for guidance, but somehow, untill now I can't log my Win2000 Profesional into the PDC server. I'm using Debian sid kernel 2.6.5, Samba 3.0.2a and a Win2000 box as client. I think there's nothing wrong with my smb.conf ( I guess...

Tom\All Has anyone heard of this log analizer and have it up and running? If so is it easy to setup and use? Description form this page http://gege.org/iptables/ IPTables log analizer (TODO : find a nice name for it) displays Linux 2.4 iptables logs (rejected, acepted, masqueraded packets...) in a nice HTML page (it support rough netfilter logs but also Shorewall and Suse Firewall logs).

Hi. I'm trying to analyse information from a large database using R. I have some problems with quotes during the generation of strings. Setting: I extract data from a lot of sampling location (chemical data on water quality) and for each location I have a date of sampling and a value. I want to put everything in a list such that for each sampling point (say OS1) I have two columns

I have some questions about how the playlist handling works in ices2. I'm trying to decide whether I want to use the script option within ices or set up a cron job that writes a new playlist.txt every so often. I play live recordings and want to minimize any gaps between files, so the internal scripting option seems like it would introduce even longer gaps than occur with straight

Hi: I've tried to install centos 4.3 in a raid array, setuped on bios as mode "Adaptec". The chip is ICH7R but centos always sees 2 drives instead of the array that I create. I've contacted Supermicro support and they gave me this link ftp://ftp.supermicro.com/driver/SATA/Adaptec_ICH7R/Linux/Redhat/ , but the disk drivers I tried to use with centos 4.3 did not work, saying that
