similar to: Summary: Archetypal Analysis in R

Is a library available for R that includes algorithms for something called "archetypal analysis," a method similar to principal components analysis that is designed to find "archetypes" or "pure types" from multidimensional data. I have contacted one of the authors who has written about archetypal analysis but thought I'd check here also. Thanks. Loren

Hi, I'm new to R. I'm trying to install R-0.64.0 on FreeBSD 2.2.8 (also new to FreeBSD). First, I run ./configure and then make. Make gives me an error message because it cannot find "eda.so" when trying to link it with line.o and smooth.o (see output below). I would appreciate it if somone could help me to fix this error. Thanks. Loren AFTER RUNNING CONFIGURE: R is now

Thanks for your help Duncan. Your last comment helped me to figure out what FreeBSD was doing differently than Linux/Solaris. This fix worked on a machine with Python 2.1, R 1.3.1 and FreeBSD 4.1. Here are the details: The pthreads fix: I added '-lc_r' to the PKG_LIBS definition in src/Makevars.in. The FreeBSD 'man pthread' page suggests that adding -pthread to the gcc statement

I'm trying to install an R package that arrived in a package.tar.gz file. I use: R INSTALL -l /home/adele/packagedir package.tar.gz and I get: ERROR: cannot extract package from package.tar.gz The author of the package assures me that the same command works for his version of solaris and R. He has solaris 5.7 and R 1.4.1, while I have solaris 5.8 and R 1.4.1. Does anyone know

Dear all, Version 4.3-0 of the randomForest package is now available on CRAN (in source; binaries will follow in due course). There are some interface changes and a few new features, as well as bug fixes. For those who had used previous versions, the important things to note are: 1. there's a namespace now, and 2. some functions have been renamed. The list of changes since 4.0-7 (last

I'd like to use the resources() function described on p. 151-152 of S Programming by Venables and Ripley (2000), but I don't have access to S and don't know whether R's memory functions (e.g., gc()) can be used instead of mem.tally.reset() and mem.tally.report(). In order to implement the resources() function in R, should I look for the C source for these S functions and wrap them

I've used R for a couple of years on FreeBSD with few problems. Recently, a couple of the contributed packages seem to have difficulty finding symbols in the shared libraries. Currently, I'm running R 1.3.1 on FreeBSD 4.4. I've tried setting LD_LIBRARY_PATH to /usr/local/lib and some other things. The packages I've had trouble with are: Matrix 0.3.15 RODBC 0.8.3 RSPython 0.3

A new version of the randomForest package is now available on CRAN. The DESCRIPTION is: Package: randomForest Title: Breiman's random forest for classification and regression Version: 3.4-1 Depends: R (>= 1.5.0) Author: Fortran original by Leo Breiman and Adele Cutler, R port by Andy Liaw and Matthew Wiener. Description: Classification and regression based on a forest of trees using

We are organizing three projects to honor Leo Breiman this year. First, Salford Systems' Data Mining Conference will open with a special session devoted to his scientific contributions. Second, we would like to construct Leo's scientific "family tree," identifying Leo's students, collaborators, and others whose work has been influenced in an important way by Leo's

Hello R-devel: I have written a package, called "woods", that does classification trees (R function CT), and currently, only the most basic functionality of Random Forest, e.g. bagged trees with choices about sample size, with/without replacement, size of (random) subset of covariates drawn when nodes are split. My reason for writing this is twofold. First, I wanted to base this

Hi Sir/Madam, I'm a researcher in university of Guelph, Canada and now considering using R to do some data analysis. I'm wondering whether there is a library available in R that includes algorithms for "archetypal analysis"? This is a method quite similar to principal components analysis that is designed to find "archetypes" or "pure types" from

Dear R users, I've just released a new version of randomForest (available on CRAN now). This version contained quite a number of new features and bug fixes, compared to version prior to 4.0-x (and few more since 4.0-1). For those not familiar with randomForest, it's an ensemble classifier/regression tool. Please see http://www.math.usu.edu/~adele/forests/ for more detailed information,
