/main/dbi/r-cran-dbi

GNU R package providing a generic database interface

A generic database interface (DBI) definition for communication between R and relational database management systems -- similar to Perl's DBI system. All classes in this package are virtual and need to be extended by the various R/DBMS implementations as e.g. RMySQL.

/main/erm/r-cran-erm

GNU R package for 'extended Rasch modelling'

eRm fits Rasch models (RM), linear logistic test models (LLTM), rating scale model (RSM), linear rating scale models (LRSM), partial credit models (PCM), and linear partial credit models (LPCM). Missing values are allowed in the data matrix. Additional features are the ML estimation of the person parameters, Andersen's LR-test, item-specific Wald test, itemfit and personfit statistics including infit and outfit measures, various ICC and related plots, automated stepwise item elimination, simulation module for various binary data matrices. An eRm platform is provided at R-forge (see URL).

Transition Package, ess to elpa-ess

The ESS addon package for Emacs has been elpafied. This dummy package helps ease transition from ess to elpa-ess.

/main/ess/elpa-ess

Emacs mode for statistical programming and data analysis

"Emacs Speaks Statistics" (ESS) is an add-on package for emacs text editors such as GNU Emacs and XEmacs. It is designed to support editing of scripts and interaction with various statistical analysis programs such as R, S-Plus, SAS, Stata and OpenBUGS/JAGS. Although all users of these statistical analysis programs are welcome to apply ESS, advanced users or professionals who regularly work with text-based statistical analysis scripts, with various statistical languages/programs, or with different operating systems might benefit from it the most. . The rationale for developing ESS is that most statistical analysis systems provide a more or less sophisticated graphical user interface (GUI). However, their full power is only available using their scripting language. Furthermore, complex statistical analysis projects require a high degree of automation and documentation which can only be handled by creating statistical analysis scripts. Unfortunately, many statistics packages provide only weak text editor functionality and show major differences between them. Without a unified text editor user interface additional effort is required from the user to cope with limited functionality and with text editor differences. . Therefore, emacs editors and the ESS package provide the following major features: - Support for various operating systems Examples: Linux, Unix, Mac OS X and MS Windows - Working environment based on emacs Examples: File Manager (Dired), File Transfer Client/Telnet Client (Tramp), Multiple Clipboards (registers), Bookmarks, Abbreviations, and many others - Support for various statistical analysis languages Examples: R, S-Plus, SAS, Stata and OpenBUGS/JAGS Examples: Keybindings, Abbreviations, Syntax highlighting, Code formatting, Commenting, Submitting scripts, Displaying results and Searching documentation . ESS is freely available under the GNU General Public License (GPL). For further technical and legal information please refer to the ESS Manual.
