Hi All, I am still learning R, but making, IMO, great strides. I learned about Kohonen/Self-Organizing Maps in class and I would like to try to replicate some of the things we have seen in class. Below is my code. I am trying to create a u-matrix. In the documentation on page 9 it appears the type of plot, dist.neighbours should do the trick, however, I am getting an error: (Error in

Hi All, I am new to R, but it has been a lot of fun learning as I go and have been blow away by what it can do. Came across this example and wanted to see if ggplot2 or some other visualization package could make this sort of graphic.

Hi Everyone, I was hoping someone could help me with the settings for Tinn-R. I see in the screen shots that it has syntax help, or something similar (tips on what functions, etc). I can not seem to get this to turn on in the program, and I am wondering if I have to set up a few options. I quickly read through the help and could not figure it out. Many thanks! - Brock P.S. It appears as

Hi Everyone, I am relatively new to R, but I want to try to learn how to use it and potentially replace the other commercial packages I have learned to use over the years. That said, I need to get at data in databases, more specifically, MySQL. I installed the RMySQL package without error, but when I try to load it, I get the following error: > library(RMySQL) Loading required package: DBI

Hi all, Can anyone help me setup this package so I can use it. I am getting errors with the Rgraphviz package and have tried a number of ways to get this to work. Any help will be greatly appreciated! I am sorta new to R but have been actively trying to get into using it as my main analysis software. Thanks, Brock [[alternative HTML version deleted]]

Hi all, I am new to R, but with the help I have received thus,I have already been able to work through a bunch of questions on my own in just a few days. I imagine my questions are relatively simple, but here she goes. 1) I am using a package where one of the objects generated represents X/Y coordinates for each observation. I have been able to plot my row names onto the graph using text()

Hi everyone, I have successfully created and analyzed my network data. I am new to R, and Network Analysis too, but I want to color my vertex based on some of the centrality measures calculated. Can someone point me in the right direction? Again, I am new to R, but given how powerful R appears to be, I figure this is probably pretty easy to do, I just wish I could figure it out. Many thanks

Hi everyone, This is my first posting and I am just starting to fumble my way thru R. I have been working thru the Arules package, and I used to be able to use the image function and I get the following message: Error in image.default(basket2) : 'z' must be a matrix I used to be able to plot the image. I only started to get this error when I tried to add x and y axis labels.

Hi All, This is probably basic, but I am just starting with R and very interested in learning how to automate my reports. I am just learning about Sweave and LaTex. I am following an example from online and am getting the following error: ....."Error unizipping file....unzip not found". I am not a programmer by any stretch, but I realize that the package is either not recognizing

I have just started playing around with Samba and have run into a mental block / learning hurdle Here is what I have I have a WinNT box that acts as a PDC for a domain (mydomain for the sake of this post). Within 'mydomain' I have several workgroups (wg1, wg2, wg3, etc) Now here is where I get confused. I am trying to set up the Samba Server so it will work as follows [general] this

It would be great to know if and where an R code for Common Principal Component Analysis is available.

on our cluster that has been running lustre for about 1 month. I have 1 MDT/MGS and 1 OSS with 2 OST''s. Our cluster uses all Gige and has about 608 nodes 1854 cores. We have allot of jobs that die, and/or go into high IO wait, strace shows processes stuck in fstat(). The big problem is (i think) I would like some feedback on it that of these 608 nodes 209 of them have in dmesg

Is there instructions on how to use the patchless client on RHEL4 ? For version 1.6.2 We would prefer a rpm, but we are not scared of doing a build if needed. Brock Palen Center for Advanced Computing brockp at umich.edu (734)936-1985

Dear all, Can anyone point me to a package that can perform Common principle components? Thank you. Jos?? P. Granadeiro

Hello, I've been trying to calculate home range sizes (for Icelandic geese!) using minimum convex polygons with the adehabitat package. I've tried to use the R code shown by demo(homerange) in adehabitat and when that didn't work I've fiddled around with it but to no avail...Below is the output of the demo that I've attempted to follow, followed by a subset of my data (for one

Is it possible to browse multiple workgroups on two or more subnets? I have set up samba on either end of a VPN and can browse successfully from either end, but only in the workgroup that samba is configured for. Can Samba be a member of more than one workgroup at the same time? Looking in browse.dat I can see all the machines in samba's workgroup and also the other workgroups, but not the

Hello all, I'm going to feel dumb if rsync can already do this, but I honestly haven't found anything to indicate that. I would like to be able to store diffed files in a separate directory on the receiver so it makes doing an incremental backup easy and efficient. Let me explain: Day 1: take a full backup of a directory: rsync -r ./source/ ./dest/ Day 2: Diff the contents of ./source/

Can someone recommend a good web host for ROR? -- Posted via http://www.ruby-forum.com/.

Hi there, there is a problem (which as far as i know) is already known with rsync on FreeBSD: it is not possible to rsync neither fifos nor unix domain sockets (note that you have to be root there): # mkfifo test # file test test: fifo (named pipe) # rsync -a test test2 mknod test2 : Invalid argument rsync error: some files could not be transferred (code 23) at main.c(620) # file /var/run/log
