Discriminant Adaptive Nearest Neighbor
Dear R users,
Is there anyone who is aware of a R or S package that has Discriminant
Adaptive Nearest Neighbor (DANN) classification by Hastie and Tibshirani?
I have used the search services in R website but no luck.
Thanks in advance!
Jonathan

Nearest Neighbor Algorithm in R -- again.
Several of the methods I use for analyzing large data sets, such as
WinGamma: determining the level of noise in data
Relief-F: estimating the influence of variables
depend on finding the k nearest neighbors of a point in a data frame or
matrix efficiently. (For large data sets it is not feasible to compute
the 'dist' matrix anyway.)
Seeing the proposed solution to "[R] distance

fast nearest-neighbor in R?
Is fast nearest-neighbor functionality available in R?
I was thinking of something along the lines of what's
currently in S+SPATIALSTATS.
Thanks for any information anyone might have on this.

Speeding up simulation of mean nearest neighbor distances
I've written the function below to simulate the mean 1st through nth
nearest neighbor distances for a random spatial pattern using the
functions nndist() and runifpoint() from spatsat. It works, but runs
relatively slowly - would appreciate suggestions on how to speed up
this function. Thanks. --Dale

Sparse KMeans/KDE/Nearest Neighbors?
hi,
I have a dataset (the netflix dataset) which is basically ~18k columns and
well variable number of rows but let's assume 25 thousand for now. The
dataset is very sparse. I was wondering how to do kmeans/nearest neighbors
or kernel density estimation on it.
I tired using the spMatrix function in "Matrix" package. I think I'm able to
create the matrix but as soon as I pass

glmnet 1.9-3 uploaded to CRAN (with intercept option)
This update adds an intercept option (by popular request) - now one can fit a model without an intercept
Glmnet is a package that fits the regularization path for a number of generalized linear models, with with "elastic net"
regularization (tunable mixture of L1 and L2 penalties). Glmnet uses pathwise coordinate descent, and is very fast.
The current list of models covered are:

LDA in R: how to extract full equation, especially constant term
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

Discriminant Analysis - Obtaining Classification Functions
Hello!
I need some help with the linear discriminant analysis in R.
I have some plant samples (divided into several groups) on which I
measured a few quantitative characteristics. Now, I need to infer some
classification rules usable for identifying new samples.
I have used the function lda from the MASS library in a usual fashion:
lda.1 <- lda(groups~char1+char2+char3, data=xxx)

k nearest neighbor prediction
Hi there fellow R-users,
Does anyone know if there is a package for k nearest neighbours prediction
as opposed to classification? I have found the package knncat but can't see
a way to adjust it to predict a continuous variable.
Any help would be great,
Regards

About Omega in pda()
** High Priority **
Hello R users
My issue is both theorical and technical.
I would like to run a penalised discriminant analysis with the fda() function, but I don''t know all the details of splines theory.
I try on the example of the phonems from the article "Penalised Discriminant Analysis" of Hastie, Buja and Tibshirani 1994 : 5 groups and 256 variables.

Collapsing solution to the question discussed above: Re: multi-class classification using rpart
You could break your 3 class problem into several (2 or 3) 2 class problems,
and then use Andy's suggestion (see the CART book). There are several ways
to break the problem into 2 class problems, and several ways to combine the
resulting classifiers. Tom Dietterich, Jerry Friedman, Trevor Hastie and Rob
Tibshirani, among others, have articles on the question, in places like
