I''m trying to setup a bottlekneck scenario so I can see the effects of the RED qdisc on a congested interface. My example simulation code is at the bottom of this email if someone wants to see it. The following is a snippet form TCSIMs output. 0.602000 E : 0x80bc080 40 : inputB_eth0: 45000028 00000000 40060000 ... 0.602000 D : 0x80bc080 40 : inputB_eth0: 45000028 00000000 40060000 ...

Are there any functions available to calculate sunrise and sunset times for given latitude,longitude and dates? If not, I'll appreciatte any pointers to C code I could use/port. Thanks, Angel

Hi All, I am experimenting with using binary data (1, 0) in the kohonen package. I would like either 1 or 0 to be mapped in SOM, but the package gives me 1 or 0 (as expected), but something in between. I am not scaling the binary data, but still there are in-between values. Can anybody suggest a way to keep the data binary, even in the SOM plot? Thanks a lot. George

> first <- data.frame(a=1:3, b=4:6) > second <- data.frame(b=7:9, c=10:12) > third <- merge(first, second, by="b", all=TRUE) > third b a c 1 4 1 NA 2 5 2 NA 3 6 3 NA 4 7 NA 10 5 8 NA 11 6 9 NA 12 It's easy to replace the Nas with whatever value you want. No, merge() does not work with more than two data sets at a time. Andy From: mtb954 at gmail.com

In the name of Allah. hello, how are you? I sent a mail for you,yesterday but I didn't recieve to my aim. I need to some data frames in version 1.7.0 such as "florida","Barley","rainforest" and some others. I don't know these data frames are in which library. I typed "data(package = .packages(all.available = TRUE))" that was in "data()"

Hi all, I have a question about the SOM routine. You can either supply the initial representatives for the lattice yourself or else they are chosen randomly from the dataset. Is it possible to pass the random-seed as an argument somehow, when choosing the random initialisation of the lattice? As it is now, each time I run a SOM on a dataset with the same settings the resulting SOM will still

Hi. Three years ago, I've read the question of availability of SOM library for R using Kohonen's SOM_PAK in this mailing-list. This answer was no availability. And no package dealing with SOM in CRAN. Is this situation same? Could you tell me availability this library? Best Regards.

I am trying to use SOM package to cluster some gene expression data. I got stuck with 2 questions and can't not find any documents to resolve these matters. I would really appreciate if anybody can shed some sort of light. Q1. I clustered the data using SOM function and plotted it using plot function. But I can't figure out how I can list the data elements belongs to different clusters. I

Hi All, I'm looking for some reference paper about SOM (self organizing map) algorithm. I tried the paper which is mentioned in the help page of function "som (package:som)": http://www.cis.hut.fi/research/papers/som_tr96.ps.Z But I can't open it for some reason. Could you please help me with it ? Thanks a lot! [[alternative HTML version deleted]]

R version 2.9.2 (2009-08-24) - for windows > library(SOM) Error in library(SOM) : there is no package called 'SOM' Where can I get the SOM library from?

Is there an implementation of the SOM ('Self Organizing Map') procedure in R ? I am aware of the implementations of Sammon mapping, multidimensional scaling and, somewhat peripherally, principal curves and projection pursuit .. but not SOM per se as far as I can see. Am I missing something? --------------------- for anyone interesed in SOM I found Samuel Kaski's thesis

The (slow) SOM code can be found on my web page (towards the bottom) http://peabody.vanderbilt.edu/depts/psych_and_hd/faculty/wallern/ On Thu, 1 Mar 2001, John Aitchison wrote: > > Is there an implementation of the SOM ('Self Organizing Map') procedure in > R ? > > I am aware of the implementations of Sammon mapping, multidimensional > scaling and, somewhat

I have a data set with 10 variables, and about 8000 instances (or objects/rows/samples). In addition I have one more ('class') variable that I have about 10 instances for, but for which I wish to impute values for. I am a little confused how to go about doing this, mostly as I'm not well-versed in it. Do I train the SOM with a data object that contains just the first 10 variables

I have a 1945 Bottle of Vintage Port Specially Bottled for the President, Richard M. Nixon. I have a picture, just don't know how to post it on this forum. The label says Borges&Irmao and from Portugal. Any idea what this is worth?

I have several too and I also see this problem on occasion. Like you say, it is fairly rare and I can't pinpoint a cause or tell if it is a symptom of something else. I think I wrote to tech support about it but never heard anything. I'm wondering how long they will continue to support the phone. -Nate > -----Original Message----- > From: Jerry Geis

We've been running 1.1 rc3 now for about a month, and overall it's been very fast and stable. There is however an Index-related problem that keeps cropping up which prevents a user from accessing their mailbox until their Indexes are manually removed. Somehow, an Index becomes problematic, and Dovecot hangs forever when the mailbox is accessed. It manifests when a user logs in and
