It is not clear to me that one can. If the singular value decomposition of A is the triple product P d Q', then the singular value decomposition of A'A=S is Q d^2 Q'. The information about the orthonormal matrix P is lost, is it not? ********************************************************** Cliff Lunneborg, Professor Emeritus, Statistics & Psychology, University of Washington,

I would have expected the function getAnywhere to have behaved differently in the following: > search() [1] ".GlobalEnv" "file:C:/R/Rdata/miya/.Rdata" [3] "package:boot" "package:methods" [5] "package:ctest" "package:mva" [7] "package:modreg"

To follow up on my previous question, suppose a user R session wants to unload one workspace and load another within an R session. Is the following the correct sequence? 1. save.image() to save the current workspace as .Rdata in the current working directory. 2. rm(list=ls()) to remove everything from the workspace. 3. setcwd("xxx") to set the new working directory. 4.

Hello R-users, is it possible to navigate from one workspace to the other from within an R session or does one has to close R and restart it from the directory where resides the desired workspace? For example from Splus I have this little function, see at the end, which I used all the time to navigate between valid Splus directories. I find this particularly usefull when I develop new

Hello Regarding ownership on the destination: rsync's man page indicates that when synchronizing files to a remote host, -o implies the --numeric-ids option, which makes perfect sense aince the named users/groups may not exist on the destination host. The problem I have is that the files created on the destination still appear to be owned by the local user (server1) on the rsync

I am having difficulty coming to grips with Appendix B.2 of the otherwise very useful "An Introduction to R" and the related help file for Startup. I am running RGui 1.6.0 on a Windows 2000 machine from the default installation. How the concepts discussed in B.2 and the Startup help file relate to what I see on my machine is something of a mystery. I quote from the Startup file:

Hi, this is both a statistical and a R question... what would the best way / test to detect an outlier value among a series of 10 to 30 values ? for instance if we have the following dataset: 10,11,12,15,20,22,25,30,500 I d like to have a way to identify the last data as an outlier (only one direction). One way would be to calculate abs(mean - median) and if elevated (to what extent ?) delete the

Dear R users, I'm interested in measuring the stability of a heirarchical clustering, of the overall clustering and finding sub clusters (from cutting the heirarchical clustering at different levels) which demonstrate stability. I saw some postings on the R help from a while back about bootstrapping for clustering (using sample and generating a consesus tree with a web based tool CONSENSE)

Gents, Under 4.3 and the associated kernel it took 17 seconds to recompile my entire application on my amd 4800+ X2. Down from 1 minute and 20 seconds on my old platform. I just tried under the new 2.6.9-42 kernel and it is 15 seconds. So that modification to the kernel for disk improvement seemed to help my compile time... Just sharing... Great work on 4.4. Jerry

Hello, In the latest 'Scientific Computing World' magazine (issue 78, p. 22), there is a review on free statistical software by Felix Grant ("doesn't have to pay good money to obtain good statistics software"). As far as I know, this is the first time that R is even mentioned in this magazine, given that it usually discuss commercial products. In this article, the analysis

Dear useRs,Is there a command or package in R to do heirarchical clustering by "modified ward method"??regardseliza [[alternative HTML version deleted]]

Hi Guys I have been taking a close look at some networking opportunities which are being frustrated by the limits which are imposed by NAT. In particular the constraints impose by the embargo on double NATing have an impact for a project I am working on. Has anyone ever seen anything which I would conceptually describe as a reverse NAT proxy? What I want to be able to do is to be able to create

I'm using the dovecot-stable from 7/30, authenticating against an OpenLDAP server. From time to time, dovecot stops responding to new queries.

Hello, I'm modeling a watershed, and have a file linking individual tributaries - the name of each tributary and the water body into which it flows (which can be a tributary of another water body). I want to use this to build a tree data structure (a root, and then child nodes, linked to further child nodes, etc.). Is there a package that builds and traverses such data structures? Thanks,

Also noteworthy: the air moving through a hose can cause a vacuum's hose or attachment to build up a static charge, which is another reason it can be a bad idea to use a vacuum in a computer.

I own a recording studio. We do a weekly live concert broadcast to Facebook using Wirecast software. There is an internet radio station that uses icecast that wants to carry the audio from my broadcast live. I have no idea how to get the audio to them. I use Mac computers. Can someone help me with that. Cliff Witherspoon Red Arrow Entertainment 864-613-4201

Thanks for the help. Will work on that.

Hi All I received a raw data set with one record per tennis player (both male and female) and then i cured it by aggregation i.e by 4 age groups, 2 gender levels and 6 income levels. Gender and Income are categorical variables. Please advise me how to use 'R' to model this data set (Actually, i want to know the right regression technique and steps to do that, including removing
