Package RJSONIO updated to version 0.8-1 with previous version 0.7-3 dated 2011-06-06

Title: Serialize R objects to JSON, JavaScript Object Notation
Description: This is a package that allows conversion to and from data in Javascript object notation (JSON) format. This allows R objects to be inserted into Javascript/ECMAScript/ActionScript code and allows R programmers to read and convert JSON content to R objects. This is an alternative to rjson package. That version is too slow for converting large R objects to JSON and is not extensible, but a very useful prototype. It is fast for parsing. This package uses methods, vectorized operations and C code and callbacks to R functions for deserializing JSON objects to R. Verison 0.4 of this package uses a new native parser, implements the transformation code in C and allocates memory efficiently (rather than concatenating because of event driven parsing). The result is a significantly faster parsing of large JSON documents.

Package tabplot updated to version 0.10-1 with previous version 0.10 dated 2011-07-29

Title: Tableplot, a visualization of large statistical datasets
Description: A tableplot is a visualisation of a (large) statistical dataset with a dozen of variables, both both numeric and categorical. Each column represents a variable and each row bin is an aggregate of a certain number of records. Numeric variables are visualized as bar charts, and categorical variables as stacked bar charts. Missing values are taken into account. A GUI has been implemented which is used to easily customize the tableplot. Also supports large ffdf datasets from the ff package.

Package npRmpi updated to version 0.40-9 with previous version 0.40-7 dated 2011-06-09

Title: Parallel nonparametric kernel smoothing methods for mixed data types
Description: This package provides a variety of nonparametric (and semiparametric) kernel methods that seamlessly handle a mix of continuous, unordered, and ordered factor data types. This package is a parallel implementation of the np package based on the MPI specification that incorporates the Rmpi package (Hao Yu ) with minor modifications and we are extremely grateful to Hao Yu for his contributions to the R community. We would like to gratefully acknowledge support from the Natural Sciences and Engineering Research Council of Canada (NSERC:www.nserc.ca), the Social Sciences and Humanities Research Council of Canada (SSHRC:www.sshrc.ca), and the Shared Hierarchical Academic Research Computing Network (SHARCNET:www.sharcnet.ca).

Package FrF2 updated to version 1.2-5 with previous version 1.2-4 dated 2011-07-23

Title: Fractional Factorial designs with 2-level factors
Description: This package creates regular and non-regular Fractional Factorial designs. Furthermore, analysis tools for Fractional Factorial designs with 2-level factors are offered (main effects and interaction plots for all factors simultaneously, cube plot for looking at the simultaneous effects of three factors, full or half normal plot, alias structure in a more readable format than with the built-in function alias). The package is currently subject to intensive development. While much of the intended functionality is already available, some changes and improvements are still to be expected. Suggestions are welcome.
