Package ddepn updated to version 1.6 with previous version 1.5 dated 2010-12-12

Title: Dynamical Deterministic Effects Propagation Networks: Infer signalling networks for timecourse RPPA data.
Description: Given a matrix of reverse-phase-protein-array timecourse data, containing one or more experimental measurements for the signalling patterns among proteins in cells, the package attempts to model the time-dependent propagation of active and passive states depending on a network. The most likely network structure given the data is reconstructed.

Package RgoogleMaps updated to version 1.1.9.5 with previous version 1.1.9.4 dated 2011-01-08

Title: Overlays on Google map tiles in R
Description: This package serves two purposes: (i) Provide a comfortable R interface to query the Google server for static maps, and (ii) Use the map as a background image to overlay plots within R. This requires proper coordinate scaling. NOTE: To do anything but downloading static map tiles, RgoogleMaps needs EITHER rgdal OR ReadImages OR rimage installed ! Such an OR dependency is difficult to express in the Depends field, so I moved those packages to suggested. rgdal is your package if you prefer png file format and ReadImages or rimage if you prefer jpg format. In the latter cases, you will also need the libjpeg library installed.

Package RcppArmadillo updated to version 0.2.15 with previous version 0.2.14 dated 2011-03-04

Title: Rcpp integration for Armadillo templated linear algebra library
Description: R and Armadillo integration using Rcpp Armadillo is a templated C++ linear algebra library (by Conrad Sanderson) that aims towards a good balance between speed and ease of use. Integer, floating point and complex numbers are supported, as well as a subset of trigonometric and statistics functions. Various matrix decompositions are provided through optional integration with LAPACK and ATLAS libraries. A delayed evaluation approach is employed (during compile time) to combine several operations into one, and to reduce (or eliminate) the need for temporaries. This is accomplished through recursive templates and template meta-programming. This library is useful if C++ has been decided as the language of choice (due to speed and/or integration capabilities), rather than another language. The RcppArmadillo package includes the header files from the templated Armadillo library (currently version 1.1.4). Thus users do not need to install Armadillo itself in order to use RcppArmadillo. This Armadillo integration provides a nice illustration of the capabilities of the Rcpp package for seamless R and C++ integration. Armadillo is licensed under the GNU LGPL version 3 or later, while RcppArmadillo (the Rcpp bindings/bridge to Armadillo) is licenses under the GNU GPL version 2 or later, as is the rest of Rcpp.

Package penalized updated to version 0.9-35 with previous version 0.9-34 dated 2011-02-04

Title: L1 (lasso) and L2 (ridge) penalized estimation in GLMs and in the Cox model
Description: A package for fitting possibly high dimensional penalized regression models. The penalty structure can be any combination of an L1 penalty (lasso), an L2 penalty (ridge) and a positivity constraint on the regression coefficients. The supported regression models are linear, logistic and poisson regression and the Cox Proportional Hazards model. Cross-validation routines allow optimization of the tuning parameters.

Package bipartite updated to version 1.15 with previous version 1.14 dated 2010-12-21

Title: Visualising bipartite networks and calculating some (ecological) indices.
Description: Bipartite provides functions to visualise webs and calculate a series of indices commonly used to describe pattern in ecological webs. It focusses on webs consisting of only two trophic levels, e.g. pollination webs or predator-prey-webs. Visualisation is important to get an idea of what we are actually looking at, while the indices summarise different aspects of the webs topology.
Author: Carsten F. Dormann and Bernd Gruber, with additional code from Mariano Devoto, Jochen Fruend, Jose Iriondo, Rouven Strauss and Diego Vazquez, also based on C-code developed by Nils Bluethgen, Aaron Clauset/Rouven Strauss and Miguel Rodriguez-Girones.

Package rake updated to version 1.2 with previous version 1.1 dated 2010-04-12

Title: Normalize sample weights using marginal total population weights.
Description: Raking a survey dataset entails re-weighting a sample by making the sample marginal totals agree with the population marginal totals for two survey response variables. Raking is a robust technique that is often useful for dealing with nonresponse. The 'rake' package streamlines the process of Raking by creating the special 'rake' class, which is essentially a summary of the sample weights.

Package RcppArmadillo updated to version 0.2.14 with previous version 0.2.13 dated 2011-02-19

Title: Rcpp integration for Armadillo templated linear algebra library
Description: R and Armadillo integration using Rcpp Armadillo is a templated C++ linear algebra library (by Conrad Sanderson) that aims towards a good balance between speed and ease of use. Integer, floating point and complex numbers are supported, as well as a subset of trigonometric and statistics functions. Various matrix decompositions are provided through optional integration with LAPACK and ATLAS libraries. A delayed evaluation approach is employed (during compile time) to combine several operations into one, and to reduce (or eliminate) the need for temporaries. This is accomplished through recursive templates and template meta-programming. This library is useful if C++ has been decided as the language of choice (due to speed and/or integration capabilities), rather than another language. The RcppArmadillo package includes the header files from the templated Armadillo library (currently version 1.1.4). Thus users do not need to install Armadillo itself in order to use RcppArmadillo. This Armadillo integration provides a nice illustration of the capabilities of the Rcpp package for seamless R and C++ integration. Armadillo is licensed under the GNU LGPL version 3 or later, while RcppArmadillo (the Rcpp bindings/bridge to Armadillo) is licenses under the GNU GPL version 2 or later, as is the rest of Rcpp.
