Package wavelets updated to version 0.2-5 with previous version 0.2-4 dated 2009-04-22

Author: Eric Aldrich
Title: A package of funtions for computing wavelet filters, wavelet transforms and multiresolution analyses
Description: This package contains functions for computing and plotting discrete wavelet transforms (DWT) and maximal overlap discrete wavelet transforms (MODWT), as well as their inverses. Additionally, it contains functionality for computing and plotting wavelet transform filters that are used in the above decompositions as well as multiresolution analyses.

Package frontier updated to version 0.991-2 with previous version 0.991-0 dated 2009-06-18

Author: Tim Coelli, Arne Henningsen
Title: Stochastic Frontier Analysis
Description: Maximum Likelihood Estimation of Stochastic Frontier Production and Cost Functions. Two specifications are available: the error components specification with time-varying efficiencies (Battese and Coelli, 1992) and a model specification in which the firm effects are directly influenced by a number of variables (Battese and Coelli, 1995).

Package dr updated to version 3.0.4 with previous version 3.0.3 dated 2008-12-11

Author: Sanford Weisberg ,
Title: Methods for dimension reduction for regression
Description: Functions, methods, and datasets for fitting dimension reduction regression, using slicing (methods SAVE and SIR), Principal Hessian Directions (phd, using residuals and the response), and an iterative IRE. Partial methods, that condition on categorical predictors are also available. A variety of tests, and stepwise deletion of predictors, is also included. Also included is code for computing permutation tests of dimension. Adding additional methods of estimating dimension is straightforward. For documentation, see the vignette in the package. With version 3.0.4, the arguments for dr.step have been modified.

New package aroma.affymetrix with initial version 1.1.1
Package: aroma.affymetrix
Version: 1.1.1
Date: 2009-06-29
Title: Analysis of large Affymetrix microarray data sets
Author: Henrik Bengtsson , Ken Simpson , Elizabeth Purdom , Mark Robinson
Maintainer: Henrik Bengtsson
Depends: R (>= 2.6.0), R.utils (>= 1.1.6), aroma.core (>= 1.1.2), aroma.light (>= 1.12.2), R.huge (>= 0.1.6), aroma.apd (>= 0.1.3), R.rsp (>= 0.3.4), affxparser (>= 1.13.8)

Suggests: DBI (>= 0.2-4), Biobase (>= 1.16.1), preprocessCore (>= 1.0.0), GLAD (>= 1.12.0), DNAcopy (>= 1.18.0), geneplotter (>= 1.16.0), oligo (>= 1.2.2), oligoClasses (>= 1.1.0), affyPLM (>= 1.14.0), affy (>= 1.16.0), EBImage (>= 2.2.0), pdInfoBuilder (>= 1.6.0), limma (>= 2.16.3), gcrma (>= 2.10.0), gsmoothr (>= 0.1.1), HaarSeg (>= 0.0.2), dChipIO (>= 0.1.0)
Description: This package implements classes for files and sets of files for various Affymetrix file formats, e.g. AffymetrixCdfFile, AffymetrixCelFile, and AffymetrixCelSet. These are designed to be memory efficient but still being fast. The idea is to keep all data on file and only read data into memory when needed. Clever caching mechanisms are used to minimize the overhead of data IO. All of the above is hidden in the package API and for the developer (and the end user), the data is queried as if it lives in memory. With this design it is only the diskspace that limits what number of arrays can be analyzed.

Package rootSolve updated to version 1.4 with previous version 1.3 dated 2009-02-20

Author: Karline Soetaert
Title: Nonlinear root finding, equilibrium and steady-state analysis of ordinary differential equations
Description: Routines to find the root of nonlinear functions, and to perform steady-state and equilibrium analysis of ordinary differential equations (ODE). Includes routines that: (1) generate gradient and Jacobian matrices (full and banded), (2) find roots of non-linear equations by the Newton-Raphson method, (3) estimate steady-state conditions of a system of (differential) equations in full, banded or sparse form, using the Newton-Raphson method, or by dynamically running, (4) solve the steady-state conditions for uni-and multicomponent 1-D, 2-D, and 3-D partial differential equations, that have been converted to ODEs by numerical differencing (using the method-of-lines approach). Includes fortran code.

New package rankhazard with initial version 0.8
Package: rankhazard
Type: Package
Title: Rank-hazard plots
Version: 0.8
Date: 2009-06-29
Author: Juha Karvanen
Maintainer: Juha Karvanen
Requires: Design, survival
Description: Rank-hazard plots (Karvanen and Harrell, Statistics in Medicine 2009) visualize the relative importance of covariates in a proportional hazards model. The key idea is to rank the covariate values and plot the relative hazard as a function of ranks scaled to interval [0,1]. The relative hazard is plotted with respect to the reference hazard, which can be e.g. the hazard related to the median of the covariate. Transformation to scaled ranks allows plotting of covariates measured in different units in the same graph, which helps in the interpretation of the epidemiological relevance of the covariates. Rank-hazard plots show the difference of hazards between the extremes of the covariate values present in the data and can be used as a tool to check if the proportional hazards assumption leads to reasonable estimates for individuals with extreme covariate values. Alternative covariate definitions or different transformations applied to covariates can be also compared using rank-hazard plots.

Package PearsonICA updated to version 1.2-4 with previous version 1.2-3 dated 2008-10-10

Author: Juha Karvanen
Title: Independent component analysis using score functions from the Pearson system
Description: The Pearson-ICA algorithm is a mutual information-based method for blind separation of statistically independent source signals. It has been shown that the minimization of mutual information leads to iterative use of score functions, i.e. derivatives of log densities. The Pearson system allows adaptive modeling of score functions. The flexibility of the Pearson system makes it possible to model a wide range of source distributions including asymmetric distributions. The algorithm is designed especially for problems with asymmetric sources but it works for symmetric sources as well.
