Hi, Figure 13 of Emmanuel Paradis's "R for Beginners" was produced by termplot working on an aov object. The lower right-hand plot is labelled "Cook's distance plot", and I'd really like to produce a similar type of figure, but in a totally different context. (I'm not even sure what this kind of figure is called, perhaps an "impulse plot", where

Hi, Having dipped my toe into R a few times over the last year or two, in the last few weeks I've been using it more and more; I'm now a thorough convert. I've just joined the list, because although it's great, I do have this problem... I'm using linear discriminant analysis for binary classification, and am happy with the classification performance using predict(). What

Hi,. I've installed RSPerl on my Linux box. It runs all of the test scripts that I've been able to find. I've learned that I can pass in vectors of data as array-refs, and can use named parameters with R::callWithNames and a hash of names and values. The one problem that I'm left with is how to call a function from an add-on package ('ctest' in this case). I know that

I am new to R. Trying to find out how lda() {in MASS R1.8.0 Windows} was implemented in R. Does anyone know where to find out lda source code ? Thanks. Wei

Hi, Following on from suggestions made last week, I decided to install R 2.1.0 on my Linux machine. I'm running into a problem there however, as shown: make[1]: Entering directory `/d0/home/fgibbons/tmp/R2.1.0/R-2.1.0/src/library/Recommended' make[2]: Entering directory `/d0/home/fgibbons/tmp/R2.1.0/R-2.1.0/src/library/Recommended' begin installing recommended package VR WARNING:

My objective is to look at differences in two species of fish from morphometric measurements. My morphometric measurements are head length, eye diameter, snout length, and measurements from tail to each fin. I want to use discrimanant function analyis to determine if there are differences between the two species. I am familiar with R but new to discrimannt function analysis. I want to learn

Hi there. Is there a way i can have my link_to refer outsite the current controler ? I have a path /refrences/ wich lists the refrences, and i want a link_to in this template, to refer to the path /companies/show/company.id is this possible ? I have tried using: ink_to ''link'', :action => ''/companies/show'', :id => company.id but with no luck, is

Hi I am new to ruby on rails , i am trying to develop a form client form having multiple refrences to country... i.e while adding a client i can add two contact persons each have a country associated with them. However with scaffolding iam unable to refer country twice....could anyone of you shed some light as to where iam going wrong or what could be the rite way.... -- You received this

Hi , I want to set up my Redhat 6.0 Linux machine to Authenticate username and password and other information for user that received from /etc/passwd & /etc/shadow from MySQL server . How Can I do that ? any Refrences or Manual for this is helpfull :) Thanx Hamid Hashemi

I have help files in several formats. Up until now I have converted nroff files to S-Plus 6 sgml and html files using Splus doc_to_S ... (creates .sgml file) Splus HINSTALL ...

If an Rd file has only one keyword entry then the Splus sgm file made with Rdconv --type=SSgm has no keyword entries.

Question 1: Is there a way to keep an authentication to a Samba share from lasting indefinitely? I am implementing a Linux file server for a network of machines all running Windows 98 SE. (Redhat 9, Samba 2.2.7a, share-level security.) Once a user provides a valid password and connects to a Samba share, Samba allows that client machine to access that share indefinitely. In our office each

Hi everyone, I'm trying to solve a problem about how to get the Fisher's discriminant functions of a "lda" (linear discriminant analysis) object, I mean, the object obtained from doing "lda(formula, data)" function of the package MASS in R-project. This object gives me the canonical linear functions (n-1 coefficients matrix of n groups at least), and only with this

Kindly let me know the process to carry out a Linear discriminant analysis...thanks in advance Arup -- View this message in context: http://www.nabble.com/Linear-Discriminant-Analysis-tp22199424p22199424.html Sent from the R help mailing list archive at Nabble.com.

Hello, I might have missed it in the help pages, but I cannot find if something exits in a package to make discriminant analysis.

Hi list, I'm looking about lda function. I'd like to know how calcolate the value of the discriminant functions for the original datas. I see that in the result object "lda" there is $scaling a matrix which transforms observations to discriminant functions, normalized so that within groups covariance matrix is spherical. I'd like to have the value of the discriminant

I have the Rexcel package. Which of the functions do I want to run a discriminant function analysis? Or, how would I do it in R? Thanks. [[alternative HTML version deleted]]

Dear members, I am wondering if there are any functions to perform the Kernel Fisher Discriminant method, especially for multi-class problems, in R. I would appreciate any kind of information on this. Thanks for your time. Seungho Huh, Ph.D. Research Statistician RTI International North Carolina, USA [[alternative HTML version deleted]]
