Hi! I am new to R just 3 days in it and i apologize if my questions seem very trivial and consumed your valuable time. I am coding in perl and i stumbled upon R regarding plotting good statistical graphs. I tried the kmean clustering for a large matrix ,say > 150 * 150 . I tried the example code given in the tutorial to perform 2d plot # i ranges from 2 to 10 cl <- kmeans(x, i, 20)

I am trying to generate kmean of 10 clusters for a 165 x 165 matrix. i do not see any errors known to me. But I get this error on running the script Error: empty cluster: try a better set of initial centers the commands are M <-matrix(scan("R_mutual",n = 165 * 165),165,165,byrow = T) cl <- kmeans(M,centers=10,20) len = dim(M)[1] .... .... I ran the same script last night and

Hi! I'm trying to build gnugk with asterisk. Asterisk is working well with chan_h323 built with needed PWlib v.1.5.2 and open H.323 v.1.12.2. But gnugk' s installing instructions says that I need latest PWlib(1.17.1) and openh323 to get gnugk work. Now, with installed pwlib and openh323 gnugk's compiling fails and I get error 1. Do you have any working solutions with asterisk and

Hello, My name is Vincent and I have some difficulties to realize my project. Indeed, I must developp a streaming flac client/server and I have some difficulties to find detailed information about this. I chose to use the platform Ices/Icecast to do my project. I took the Vorbis streaming like example but the library has not the same structure as the flac library. So , I send this message in

Hi, I have used the kmean fucntion in R to produce some results for my analysis. I like to know the specific underlying algorithm used for the implementation of the function kmean in R. I tried looking for some documents but could not find any. I obtained the kmean result for k ranging from 2 to 10. When i did this initally it worked perfectly. When i tried running again i get the error

Please make windows go away. I am enjoying(even the frustrations)learning linux for the first time. So many packages and features, it's crazy. I like crazy but have a request for you guys. Is it possible to provide me with some documentation as to how to configure my server to be a PDC compared to Windows 2000 Advanced Server? I am having a hard time understanding samba because of how easy it

Folks! Netweb Group, Inc. fully supports connectivity to any Asterisk PBX systems you have and can provide A-Z termination with immediate effect. Any volume is good enough for us, even an amount as small as $1.00 a day will do for us. We will provide connectivity from our Softswitch IP 216.162.116.46. If anyone is interested, add this to your Asterisk IPBX and then email me for setting up a

Hi all, after a half day searching for an error, sniffing and upgrading to the newest shorewall version I give up and the problem to you.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 As I pointed out to Wilson in a private message, this appears to show that no other connection requests (other than port 3000) are being sent from the client to the server (or at least no other connection requests are being received by the Shorewall box). Wilson: Are you sure that the client is supposed to open port 3001 on the server and not the

Hi Hekuran I have installed asterisk-1.0-RC2.tar.gz, asterisk-prepaid-0.3.1 and postgresql. When I tried to call from any IAX client to another IAX client and also sip client to sip client it worked fine. And also the cdr table filled properly. Now I tried to configure asterisk-prepaid-0.3.1 with asterisk. I have compiled asterisk-prepaid-0.3.1 and also copy the configure file. I

Need your help! I'm very confised and tired, tried a lot of variants but still at the start, even lost all understanding how the permissions and masks works. Please write me a config for the following case: There is a directory: '/home/shared/door', owned by 'michael:office' shared via samba as '[door]' How can I configure the FS and samba to let 'michael'

Hi, DSCP match in /tcrules/ doesn''t work with CS6 and CS7, it provides an error "invalid value" for string and hexa values. It seems that it comes from /Chain.pm/, in the function /do_dscp/: fatal_error( "Invalid DSCP ($dscp)" ) unless defined $value && $value < 0x2f && ! ( $value & 1 ); I dont understand why "$value < 0x2f", but

As i can see, if i use Shorewall tools for blocking client traffic ('blacklist' file, 'shorewall drop') it has effect only for new connections but existed don't blocks. Can i with Shorewall stop ALL traffic for definite clients? Alex ----------- IRR.BY ('Из рук в руки – Онлайн') – крупнейший в Беларуси сайт частных объявлений. http://irr.by

Hello, I would like to use centos 6.3 to build a media server with 7 2TB drives and would like suggestions on the storage aspect. This is going to run mediaplex and function only as a media storage/streaming server. 1. If I didn't care about redundancy, would ext4 handle the size of a raid 0? 2. If I did go with the redundancy, what raid level should I use? 3. Should I use LVM? Why?

A patch to add streaming support to the FLAC XMMS plugin has been sitting on my hard drive for several months (Josh wasn't accepting patches at the time because of the Xiph move, and I've been busy/lazy since then). This weekend I'll make an effort to update it to the current cvs and send if off to Josh. That covers the client side (well, at least on platforms XMMS runs on). As far

Hi! I need to create a share that will be readoble by root only (by owner) and writeable for all. We replacing a dead Windows NT 4.0 server and there was a permission type called "Add" and our users uses this type of permission often. They creates a shares where other users can add files but can not read or even list it. I saw a thread here called "How to make "Add

Hello and sorry that I still haven?t found a solution for my problem. I need to extract the lower and upper triangle from a square matrix including the diagonal. This diagonal is not zero in that special case. I tried with as.dist w<-as.dist(w, diag = TRUE) > w 1 2 3 4 5 1 0 2 2 0 3 3 8 0 4 4 9 14 0 5 5 10 15 20 0 but found no way to keep the diagonal that is in the

I need to find solutions to a tridiagonal system. By this I mean a set of linear equations Ax = d where A is a square matrix containing elements A[i,i-1], A[i,i] and A[i,i+1] for i in 1:nrow, and zero elsewhere. R is probably not the ideal way to do this, but this is part of a larger problem that requires R. In my application it is much easier (and much faster) to generate the diagonal and
