FP growth in R?
Does anyone know of an R interface to Christian Borgelt's implementation of
the FP growth algorithm?
thanks a lot

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:

MOOC on Statistical Learning with R
Rob Tibshirani and I are offering a MOOC in January on Statistical Learning.
This “massive open online course" is free, and is based entirely on our new book
“An Introduction to Statistical Learning with Applications in R”
(James, Witten, Hastie, Tibshirani 2013, Springer). http://www-bcf.usc.edu/~gareth/ISL/
The pdf of the book will also be free.

New package for ICA uploaded to CRA
I have uploaded a new package to CRAN called ProDenICA.
This fits ICA models directly via product-density estimation
of the source densities. This package was promised on page 567 in the
2nd edition of our book 'Elements of Statistical Learning'
(Hastie, Tibshirani and Friedman, 2009, Springer) . Apologies that it is so late.
The method fits each source density by a tilted gaussian

need help for superpc package
Hi,
I am using the superpc package.
By
superpc.train (data, type="regression")
I calculated the standardized regression coefficients for measuring the
univariate effect of each feature on a continuous response y.
By
superpc.cv(compute.fullcv=TRUE, compute.preval=FALSE, n.components=3,
n.fold=10)
I used cross validation to estimate the optimal feature threshold and

Least Angle Regression packages for R
Least Angle Regression software: LARS
"Least Angle Regression" ("LAR") is a new model selection
algorithm; a useful and less greedy version of traditional
forward selection methods. LAR is described in detail in a paper
by Brad Efron, Trevor Hastie, Iain Johnstone and Rob Tibshirani,
soon to appear in the Annals of Statistics.

glmnet_1.6 uploaded to CRAN
We have submitted glmnet_1.6 to CRAN
This version has an improved convergence criterion, and it also uses
a variable screening algorithm that dramatically reduces the time
to convergence (while still producing the exact solutions).
The speedups in some cases are by a factors of 20 to 50, depending on
the particular problem and loss function.
