Package rimage updated to version 0.5-8 with previous version 0.5-7 dated 2005-01-12

Author: Nikon Systems Inc.
Title: Image Processing Module for R
Description: This package provides functions for image processing, including sobel filter, rank filters, fft, histogram equalization, and reading JPEG file. This package requires fftw-2 and libjpeg . This version doesn't require pixmap package, which the older version of rimage (private only) required. This package can be used on Unixes / MacOS X / Windows.

New package metafor with initial version 0.5-0
Package: metafor
Version: 0.5-0
Date: 2009-06-04
Title: Meta-Analysis Package for R
Author: Wolfgang Viechtbauer
Maintainer: Wolfgang Viechtbauer
Depends: R (>= 2.9.0), stats
Description: The metafor package consists of a collection of functions for conducting meta-analyses in R. Fixed- and random-effects models (with and without moderators) can be fitted via the general linear (mixed-effects) model. For 2x2 table data, the Mantel-Hanszel and Peto's method are also implemented.

Package logcondens updated to version 1.3.4 with previous version 1.3.3 dated 2009-03-04

Author: Kaspar Rufibach and Lutz Duembgen
Title: Estimate a Log-Concave Probability Density from iid Observations
Description: Given independent and identically distributed observations X(1), ..., X(n), this package allows to compute a concave, piecewise linear function phi on [X(1), X(n)] with knots only in {X(1), X(2), ..., X(n)} such that L(phi) = sum_{i=1}^n W(i)*phi(X(i)) - int_{X(1)}^{X(n)} exp(phi(x)) dx is maximal, for some weights W(1), ..., W(n) s.t. sum_{i=1}^n W(i) = 1. According to the results in Duembgen and Rufibach (2009), this function phi maximizes the ordinary log-likelihood sum_{i=1}^n W(i)*phi(X(i)) under the constraint that phi is concave. The corresponding function exp(phi) is a log-concave probability density. Two algorithms are offered: An active set algorithm and one based on the pool-adjacent-violaters algorithm.
