Author: Jing Hua Zhao and colleagues with inputs from Kurt Hornik and Brian Ripley
Title: Genetic analysis package
Description: It is designed as an integrated package for genetic data analysis of both population and family data. Currently, it contains functions for sample size calculations of both population-based and family-based designs, classic twin models, probability of familial disease aggregation, kinship calculation, some statistics in linkage analysis, and association analysis involving one or more genetic markers including haplotype analysis with or without environmental covariates.

Package msm updated to version 0.9.3 with previous version 0.9.2 dated 2009-07-18

Author: Christopher Jackson
Title: Multi-state Markov and hidden Markov models in continuous time
Description: Functions for fitting general continuous-time Markov and hidden Markov multi-state models to longitudinal data. Both Markov transition rates and the hidden Markov output process can be modelled in terms of covariates. A variety of observation schemes are supported, including processes observed at arbitrary times, completely-observed processes, and censored states.

Package fpc updated to version 1.2-6 with previous version 1.2-4 dated 2009-05-06

Author: Christian Hennig
Title: Fixed point clusters, clusterwise regression and discriminant plots
Description: Fuzzy and crisp fixed point cluster analysis based on Mahalanobis distance and linear regression fixed point clusters. Semi-explorative, semi-model-based clustering methods, operating on n*p data, do not need prespecification of number of clusters, produce overlapping clusters. Symmetric and asymmetric discriminant projections separate groups optimally, used to visualize the separation of groupings, visual cluster validation. Clusterwise linear regression by normal mixture modeling. Cluster validation statistics for distance based clustering including corrected Rand index. Clusterwise cluster stability assessment. DBSCAN clustering. Interface functions for many clustering methods implemented in R. Note that the use of the package mclust (called by function prabclust) is protected by a special license, see http://www.stat.washington.edu/mclust/license.txt, particularly point 6.

Package RCurl updated to version 1.2-0 with previous version 1.1-0 dated 2009-08-21

Author: Duncan Temple Lang
Title: General network (HTTP/FTP/...) client interface for R
Description: The package allows one to compose general HTTP requests and provides convenient functions to fetch URIs, get & post forms, etc. and process the results returned by the Web server. This provides a great deal of control over the HTTP/FTP/... connection and the form of the request while providing a higher-level interface than is available just using R socket connections. Additionally, the underlying implementation is robust and extensive, supporting FTP/FTPS/TFTP (uploads and downloads), SSL/HTTPS, telnet, dict, ldap, and also supports cookies, redirects, authentication, etc.

Package PTAk updated to version 1.1-22 with previous version 1.1-20 dated 2009-02-17

Author: Didier Leibovici
Title: Principal Tensor Analysis on k modes
Description: A multiway method to decompose a tensor (array) of any order, as a generalisation of SVD also supporting non-identity metrics and penalisations. 2-way SVD with these extensions is also available. The package includes also some other multiway methods: PCAn (Tucker-n) and PARAFAC/CANDECOMP with these extensions.
