Loadings and scores from fastICA?
Hi all, Does anyone know how to get the independent components and loadings from an Independent Component Analysis (ICA), as well as principal components and loadings from a Pricipal Component analysis (PCA) using the fastICA package? Or perhaps if there's another way to do ICAs in R? Below is an example from the fastICA manual (http://cran.r-project.org/web/packages/fastICA/fastICA.pdf)

fastICA
Hi everyone It looks like repeated runs of fastICA produce quite significantly different mixing matrices (not only in terms of sign and row order). I'm not a specialist, so would appreciate any advice on whether this should really be the case: > res3 = > fastICA(af[,2:20],4,alg.typ="parallel",fun="logcosh",alpha=1,method="C",row.norm=TRUE) colstandard >

Error in solve.default(V, W) with ProDenICA and the required sample size for stable result
Hi ALL, Recently I confronted with a error in using package ProDenICA, when let k<p (exactly the example code with k=1, http://finzi.psych.upenn.edu/R/library/ProDenICA/html/ProDenICA.html), Error in solve.default(V, W) : 'b' must be compatible with 'a' I have examined the code of function ProDenICA(), but could not find the reason. And how large is the sample size N

Independent component analysis with only one "source" of data
Hi, Looking at the fastICA library. I want to test separating out different sounds from a recorded wav file. But, I only have a SINGLE stream of data (one channel wav.) It appears as if the fastICA won't let me separate more sounds than I have columns in my data matrix. is this correct? If so, is there a work around that is commonly used? Thanks. -- Noah Silverman UCLA Department of

Explained variance for ICA
Hello, I think to use FastICA package for microarray data clusterization, but one question stops me: can I know how much variance explain each component (or all components together) ? I will be very thankful for the help. Thanks, Pavel [[alternative HTML version deleted]]

R CMD INSTALL fails where R CMD check succeeds.
This is in a 64 bit CentOS 5.6 instance at Amazon AWS with R version 2.14.1 (2011-12-22). It happens on several packages: RMySQL, RODBC, FastICA. Many other packages install just fine. Here's an example error message: * installing *source* package 'RODBC' ... ** package 'RODBC' successfully unpacked and MD5 sums checked sh: ./configure: /bin/sh: bad interpreter:

FastICA and matching variance of inputs
I have been playing around with the FastICA algorithm in R, and I have come across the following issue. I'm new to this topic, so I'm hoping someone will be able to shed some insight. We know that the variance of the Independent Components is constrained to be 1 and they are uncorrelated, so the sum of squares of the coefficients of the mixing matrix (a$A) will give the variance of the

Independent Components Analysis
A colleague suggested that some R software was available for estimating "Independent Components Analysis" (ICA) (... signal separation). If so, I''d appreciate any pointers .

Independent Component Regression issue in R

PCA with tow response variables
Hi all, I'm new to PCA in R, so this might be a basical thing, but I cannot find anything on the net about it. I need to make a PCA plot with two response variables (df$resp1 and df$resp2) against eight metabolites (df$met1, df$met2, ...) and I don't have a clue how to do... and I've only used the simplest PCAs before, like this: pcaObj=prcomp(t(df[idx, c(40:47)]))

Plotting Bivariate Normal Data
Dear list I have a vector of values that allegedly have a bivariate normal distribution. I want to create a plot that shows the values I have obtained, and the bivariate normal distribution curve for the data. Is there a way of doing this in R?

Is it possible to separate two independent components from arandom variable?
Dear Fred, If x1 and x2 are *not* normally distributed, you can use independent component analysis (ICA) which is based on the idea that x will be "more normal" than either x1 and x2 following the central limit theorem.

Lapack: SSYEV routine
Hi everyone, I am interested in using the SSYEV Lapack subroutine in a R package. Unfortunately I am not familiar with the all Lapack library and I was wondering why the routine SSYEV is not part of the R-LAPACK interface module. Is there any plan to extend the R-Lapack module in the next R release? Should I try to directly call the SSYEV routine of the external Lapack library from my R

Compiling R projects with multiple external libraries
Hi, I have just learned how to use compile and link libraries using "make" and how to create R projects using R CMD build or INSTALL. My understanding of both is somewhat limited and hence the question. I have a main library written in c which depends on other external libraries. Main library is to be called from R using .Call. The goal is to create a single R project that will

further f77/gfortran
OK: despite Dirk's very kind help, I decided that trying to deal with R configuration and Debian configuration simultaneously was too difficult. I did manage to solve my problem by reconfiguring/making/ installing all of 2.3.1 from source: ./configure F77=/usr/bin/g77 make make install A few questions inspired by this experience: (1) it seems a bit odd that R sets F77=gfortran by
