Package plink updated to version 1.1-3 with previous version 1.1-2 dated 2009-06-02

Author: Jonathan P. Weeks
Title: IRT Separate Calibration Linking Methods
Description: This package uses item response theory methods to compute linking constants and conduct chain linking of unidimensional or multidimensional tests for multiple groups under a nonequivalent groups common item design. The unidimensional methods include the Mean/Mean, Mean/Sigma, Haebara, and Stocking-Lord methods for dichotomous (1PL, 2PL and 3PL) and/or polytomous (graded response, partial credit/generalized partial credit, nominal, and multiple-choice model) items. The multidimensional methods include the Reckase-Martineau method and extensions of the Haebara and Stocking-Lord method using a single dilation parameter, multiple dilation parameters, or the Oshima, Davey, & Lee approach for multidimensional extensions of all the unidimensional dichotomous and polytomous item response models. The package also includes functions for importing item and/or ability parameters from common IRT software and ploting item characteristic/category curves or surfaces and vector plots.

Package multtest updated to version 2.1.1 with previous version 2.0.0 dated 2009-05-10

Author: Katherine S. Pollard, Houston N. Gilbert, Yongchao Ge, Sandra Taylor, Sandrine Dudoit
Title: Resampling-based multiple hypothesis testing
Description: Non-parametric bootstrap and permutation resampling-based multiple testing procedures (including empirical Bayes methods) for controlling the family-wise error rate (FWER), generalized family-wise error rate (gFWER), tail probability of the proportion of false positives (TPPFP), and false discovery rate (FDR). Several choices of bootstrap-based null distribution are implemented (centered, centered and scaled, quantile-transformed). Single-step and step-wise methods are available. Tests based on a variety of t- and F-statistics (including t-statistics based on regression parameters from linear and survival models as well as those based on correlation parameters) are included. When probing hypotheses with t-statistics, users may also select a potentially faster null distribution which is multivariate normal with mean zero and variance covariance matrix derived from the vector influence function. Results are reported in terms of adjusted p-values, confidence regions and test statistic cutoffs. The procedures are directly applicable to identifying differentially expressed genes in DNA microarray experiments.

Package bnlearn updated to version 1.4.1 with previous version 1.4 dated 2009-05-05

Author: Marco Scutari
Title: Bayesian network structure learning
Description: Bayesian network structure learning via constraint-based (also known as 'conditional independence') and score-based algorithms. This package implements the Grow-Shrink (GS) algorithm, the Incremental Association (IAMB) algorithm, the Interleaved-IAMB (Inter-IAMB) algorithm, the Fast-IAMB (Fast-IAMB) algorithm, the Max-Min Parents and Children (MMPC) algorithm and the Hill-Climbing (HC) greedy search algorithm for both discrete and Gaussian networks, along with many score functions and conditional independence tests. Some utility functions (model comparison and manipulation, random data generation, arc orientation testing, simple and advanced plots) are also included.

New package aroma.apd with initial version 0.1.6
Package: aroma.apd
Version: 0.1.6
Date: 2009-06-11
Title: A probe-level data file format used by aroma.affymetrix [DEPRECATED]
Author: Henrik Bengtsson
Maintainer: Henrik Bengtsson
Depends: R (>= 2.2.0), R.oo, R.utils, R.huge, affxparser
Description: THIS PACKAGE HAS BEEN DEPRECATED. (The (in-house) APD file format was initially developed to store Affymetrix probe-level data, e.g. normalized CEL intensites. Chip types can be added to APD file and similar to methods in the affxparser package, this package provides methods to read APDs organized by units (probesets). In addition, the probe elements can be arranged optimally such that the elements are guaranteed to be read in order when, for instance, data is read unit by unit. This speed up the read substantially. This package is supporting the aroma.affymetrix package and not intended to be used elsewhere.)

Title: Creates Random Forest and Stochastic Gradient Boosting Models, and applies them to GIS .img files to build detailed prediction maps.
Description: This package will create sophisticated models of training data and validate the models with an independant test set, cross validation, or in the case of Random Forest Models, with Out OF Bag (OOB) predictions on the training data. It will creat graphs and tables of the model validation results. It will apply these models to GIS .img files of predictors to create detailed prediction surfaces. It will handle large predictor files for map making, by reading in the .img files in chuncks, and output to the .txt file the prediction for each data chunk, before reading the next chenk of data.
