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

There are answers that could and should be applied in specific situations. At least in academia and in substantial research teams, statisticians ought to have a prominent part in many of the research teams. Senior statisticians should have a prominent role in deciding the teams to which this applies. why should it be ok to do combine high levels of chemical expertise with truly appalling

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

Olly, many thanks for suggesting htdig, you saved me a lot of time. Htdig looks better than my original idea - wget, you were right. Using htdig, I can crawl and search single website - but I need to integrate search of pages spread over 100+ sites. Learning, learning.... Htdig uses separate document database for every website (one database per URL to initiate crawling). Htdig also can merge

At wiki page: http://wiki.xapian.org/Omega I added a comment that ht://Dig looks like dead. Does anybody really use it? >From brief glance at docs I had a feeling it is not easy to configure. Maybe better crawler is GNU wget? Mature, stable, maintained? -- Peter Masiar

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

I thought R users might be interested (surprised) to hear that R will have some competition on Linux now.

I'm starting to prepare the next release. Since 0.8.3 I've made a number of changes to get working builds working on HPUX and OSF, and made some of the Windows specific bits more robust. I'd like to check that these haven't broken CYGWIN or IRIX builds, but I don't have access to these platforms. If you are able to test, it'd be most appreciated if you could. Download a

Mailman works well for our mailing lists, but the archive is unacceptable - the worst thing is lack of search function. I got one tip for this: 1) emails converted to html format with mhonarc 2) search can be done with htdig Opinions?

big congratulations to fletcher penney on his release of "multimarkdown composer". at #21-paid when i purchased it just now. i'd say $9.99 will be best in the long-term -- don't listen to people who say more -- but $7.99 is the _right_ introductory price. word-of-mouth will be what sells this pup, so you want it to flow copiously right now. -bowerbird -------------- next part

My search site, http://finzi.psych.upenn.edu, has had several problems recently, all my fault, for which I apologize. But it now seems to be running reliably, on a new computer that is much faster than the old one. It uses htdig to permit search of the Rhelp mailing list, R documents, R functions, and various combinations of these. Search has several options, including Boolean search (with AND,

I recently updated my search site at http://finzi.psych.upenn.edu It took about 7 hours with htDig, instead of the usual 3 hours. Now, when I search the "functions" index I get all sorts of non-html documents (indicated with brackets). These have never shown up before. Did htDig mogrify itself while it sat on my computer? (I didn't do anything to change it.) Or, more likely, I
