Dear r-helpers! I want to classify my vegetation data with hierachical cluster analysis. My Dataset consist of Abundance-Values (Braun-Blanquet ordinal scale; ranked) for each plant species and relev?. I found a lot of r-packages dealing with cluster analysis, but none of them is able to calculate a distance measure for ranked data. Podani recommends the use of Goodman and Kruskals' Gamma for

The Goodman/Kruskal gamma is a nice descriptive rank-order correlation statistic, often used in psychology. It is nice because it is easy to understand. It takes all pairs of values of each variable and asks whether they are congruent (S+ is the number in the same order for both variables) or discordant (S-, opposite ranking). The statistic is (S+ - S-)/(S+ + S-). It is like tau except for the

Dear List, I would like to calculate the Goodman-Kruskal gamma for the predicted classes obtained from an ordinal regression model using lrm in the Design package. I couldn't find a way to get gamma for predicted values in Design so have found previous positings suggesting to use : Rcorr.cens(x, S outx = TRUE) in the Hmisc package My question is, will this work for predicted vs

Dear list, I have a problem on calculating the standard error of Goodman-Kurskal's gamma using delta method. I exactly follow the method and forumla described in Problem 3.27 of Alan Agresti's Categorical Data Analysis (2nd edition). The data I used is also from the job satisfaction vs. income example from that book. job <- matrix(c(1, 3, 10, 6, 2, 3, 10, 7, 1, 6, 14, 12, 0, 1, 9,

Hi I need to know which package in R calculates the Goodman Kruskal's tau statistic for nominal data. Also is there any implementation for multiple classification analysis (Andrews at al 1973) in R? Any information on this would be greatly appreciated. Thank you Upasna -- --------------------------------------------------------------------- Upasna Sharma Research Scholar Shailesh J. Mehta

Lets say I have an * at my business, with 7960 SIP phones. All the sip phones are registered using their extension number (like 305), but I would also like to put my SIP URI on my business card and in a name format, not an extension number (like lee.goodman), so that the SIP URI would read lee.goodman@asterisk.company.com. How would I set this up in extensions.conf? I got

Just a quick thanks to everyone involved with samba3 dev, I upgraded last night from 3.0.7 to 3.0.9 and it went really smoothly - just had to reset the permissions on /var/spool/samba so that people could print again! (It seems to reset perms each upgrade, but at least I know this now!). We are running the following without any hassle: Sage Approch Access all ms office suite openoffice Outlook

Hello all, I wanted to announce a new R search engine I made that covers all the major R mailing lists, CRAN, r-project.org, and more. Results are tabbed, so you can refine the search. Current refinements include searching just the mailing lists, searching just introductions, and searching the web for source files ending in .R. Please send comments and suggestions. If you want to add sites to

Hi, It appears that there is no package for estimating log linear models (L. Goodman's family) for data in the form of frequency tables. Am I wrong?

Trying a different approch. Senario Raid 1 setup Bootable raid drive failed Mirror has been working for almost a month and then rebooted Now can't boot mirror drive grub not mirrored from other drive. I Fixed bootable drive. Question? Can I hook up both drives and boot fixed drive then rebuilt mirror from nonbootable drive to bootable drive? Does the raid automatically rebuilt when I

We are constructing growth charts (age/weight and age/length) for children with diagnosis that impacts weight/length. But we we don't know how to use R for producing growth charts. We are collection data of Age, Weight and Length. The data are used to produce diagnosis-specific Growth charts (like the CDC Growth Charts:

I have been trying to setup point and print on a debian testing box. I have a HP5550 printer and am trying to install the drivers through the add printer wizard, the drivers appeared to install fine. Afterwards I right clicked on the printer and clicked connect, per the SAMBA howto, this also appeared to work. When I tried to enter the properties screen of the local printer or on the share I

Hi, I am using virStorageVolDownload to download volumes for the VDSM project. What is the best approch to know domains volume? Is there an api for associating domain to its pool and then to its volumes? I was able to do that by iterating the pools and then iterating all its volume..., is there a better way? Thank you, Shahar Havivi.

I have 20+ asterisk servers and need to network them together so a phone on any of the servers can call a phone on any other server without any trouble. I can think of IAX trunks between every server. So every server will have an IAX trunk to every server and then prefix bases routing in the dialplan for each server (I can give a number to each server and use that as a prefix for that server).

Hello All: I hope I can get someone interested in this problem: Agresti in "Analysis of Categorical Data," p. 289, applies a "row and column effects model" to analyze a two-dimensional cross-classification of ordinal data. He got his results in either SAS or GLIM. Is there a way to replicate his results with R? He claims the RC model fits well with G^2(RC) = 3.57 with df =

Hi, I''m using prototype within ruby on rails. One limitation I''d like to overcome is the restriction of beeing able to update just one html elements content using from_remote_tag or link_to_remote. AFAICS this is just a restriction of the form_remote_tag/link_to_remote implementation and it''s underlying Ajax.Updater class. Right? In theorie there should be no problem,

How can I extract only the time component from an POSIXlt object? For example if I try the following it still returns both the date and time... >as.POSIXlt(tr.date[1]) [1] "2010-10-18 21:46:53" >as.POSIXlt(tr.date[1],"%H:%M:%S") [1] "2010-10-18 21:46:53" round and trunc don't help... is there an "as.Time" equivalent to as.Date ? Thanks,

Hello, Is there a great book for Ror. I am looking for a book with a step by step approch and by PROJECTS!! RoR needs to be ''practiced'', and i didn''t find those WORKING PROJECTS. Am i dreaming or is this paper exists. All the books on amazon are not amazING. They talks only about theory. Theory is fine, i mean this is RoR. But then... Thanks for those who, first,

Has anyone used Gastman/Astman successfully? I have it up and running (Gastman win32), but have a problem with the creation of end stations on the map. I'm not sure of the format of the extension to use when creating a end station icon. Services like Conference bridge and Musichonhold seem to work ok (I use 555@mainmenu and 666@mainmenu) for the Icon extensions. IAX softphone seems to work
