Omegahat RSS Feeds /myrss.rss Information about Omegahat development and releases Mon, 24 April 2006 07:00:34 PST Manually! Omegahat http://www.omegahat.org RCompression http://www.omegahat.org/Rcompression Tar facilities can work from raw vector which allows one to read an archive directly into memory and then apply the tar tools without having to write the archive to disk. This also allows us to handle bz2 tar files. RSPerl http://www.omegahat.org/RSPerl Update to handle installation better for Mac OS X and cases where the header files are not in the "usual" location. Rlibstree http://www.omegahat.org/Rlibstree Updated version of Rlibstree for suffix trees. This release includes the latest libstree distribution itself along with some changes that allow libstree to be compiled on Windows (using MinGW). A binary for the Rlibstree package is available. RDCOMClient http://www.omegahat.org/RDCOMClient Finally resolved the issue with RDCOMClient and the generic for the function names(). Binary available from the www.omegahat.org/R repository. XML http://www.omegahat.org/RSXML New version of the XML package with several enhancements. See Changes file. Sxslt http://www.omegahat.org/Sxslt New features in the Sxslt package. Google Earth example http://www.omegahat.org/GoogleEarth Example of generating XML for Google Earth from within R and using Google Earth to display temperature data for four time periods. Sxslt http://www.omegahat.org/Sxslt Features for accessing XSL code/templates from R and generally mixing the programming between XSL and R. XML http://www.omegahat.org/RSXML Significant additions of tools to create XML content. Rcompression http://www.omegahat.org/Rcompression Added facilities for accessing entries in a GNU zipped tar archive (e.g. tar.gz, .tgz files). XML http://www.omegahat.org/XML Added features for using DOM-style processing on sub-nodes within the event-driven SAX parsing model. RSPython patch http://www.omegahat.org/RSPython Fixed bug in setting the relevant environment variables for run-time. Thanks to Peter Kleiweg. Rcompression update http://www.omegahat.org/Rcompression Added functionality to get information about the entries in a zip file as a list or data frame. XML package release http://www.omegahat.org/RSXML Added ability to apply a function to elements in a node set returned from an XPath query in getNodeSet() before they are returned, avoiding an extra loop in R. Ryacas release http://www.omegahat.org/Ryacas Release of Ryacas, an interface between R and yacas, the symbolic algebra system. Source package and binaries for R-2.3.1 and R-2.4.0 for Windows available from via install.packages(). Rcompression initial release http://www.omegahat.org/Rcompression An intial version of a package that interfaces to zlib and the bzip2 library to do in-memory compression and decompression of content without having to use files. Rcurl update (0.7-0) http://www.omegahat.org/Rcurl Mechanism for reading binary data in the HTTP response. And interface for uploading files in postForm(). Sxslt release http://www.omegahat.org/Sxslt Version that works for R-2.4.0 development and earlier versions. Paper on RCurl http://www.omegahat.org/RCurl/RCurlJSS.pdf Paper submitted to JSS about the RCurl package. XML release http://www.omegahat.org/RSXML (Experimental) New structures for representing a tree which use hash tables/environments rather than lists of lists and thus allow one to identify parent and ancestor nodes and traverse the tree more generally. Also added encoding argument to saveXML() generic needed in Sxslt. RSPerl release http://www.omegahat.org/RSPerl Bug fix that affected calling anonymous R functions from Perl, i.e. within a Perl script that had a reference to an R function rather than its name within an R environment. RSPerl release http://www.omegahat.org/RSPerl This a new release of the RSPerl package with numerous chages to make it back-compatible with handling scalar references to arrays, making it easier to setup for calling Perl from R, ... RwxDevice http://www.omegahat.org/RwxDevice A basic implementation of an R graphics device using wxWidgets as the toolkit. This will be used with the wxWidgets bindigs for R that are being developed and also as a regular stand-along device in its own right. RGCCTranslationUnit http://www.omegahat.org/RGCCTranslationUnit Significant steps in reading translation unit files describing source code using Perl module from within R via RSPerl. This sets the stage for creating automated bindings to C/C++ data structures and routines. RwxWidgets http://www.omegahat.org/RwxWidgets Initial work on an interface to the wxWidgets toolkit for GUI development. Currently, this is manually created, but the translation unit mechanism will allow us to readily generate interfaces to the remaining classes. Currently, we have access to wxGrid (a data grid/table) and the HTML widget, along with the ability to handle links and special tags within HTML and embed widgets. This is being done as part of the StatDocs project. RSPerl (0.8-1) http://www.omegahat.org/RSPerl New version with some bug fixes to handle conversion from Perl to R better. XML (0.99-5) http://www.omegahat.org/RSXML Exported append.xmlNode and append.XMLNode XML (0.99-4) http://www.omegahat.org/RSXML Minor update to fix a bug in xmlOutputDOM dealing with comments. Sxslt (0.5-0) http://www.omegahat.org/Sxslt A new release of Sxslt with much improved support for running XSLT from within R. One can register extension functions from R more easily and use them directly within XSLT embedded within R. Specifying parameters in applying stylesheets behaves correctly and general improvements. SJava update (0.69-0) http://www.omegahat.org/RSJava A new release of SJava with and enhancements for the converters to allow the caller to specify an R function or native routine to perform the conversion of the return value in a .Java() call.

Additionally, the dependency on the old version of antlr has now been removed. (.OmegahatExpression() currently does not work, as a result.) SJava update (0.68-1) http://www.omegahat.org/RSJava A new release of SJava with some bug fixes and enhancements for the converters. RSPerl and linking Perl modules http://www.omegahat.org/RSPerl/FAQ.html#PerlModules When Perl is run inside R, and one wants to load a Perl module which uses C code, special handling is needed which the RSPerl package tries to do automatically. To exclude some C-based modules from this treatment, you can specify which ones to include, or none. XML http://www.omegahat.org/RSXML/ Update to the XML package that performs more checking on the libxml2 version installed to determine if it is appropriate. RDCOMEvents http://www.omegahat.org/RDCOMEvents New versions of RDCOMEvents to fix a bug in findConnectionPoint(). RDCOMClient http://www.omegahat.org/RDCOMClient/Docs/introduction.html Example and discussion of using R to program forms on Excel worksheets. Rexif http://www.omegahat.org/Rexif Rexif is a package for reading meta-data from images taken by digital cameras. This provides information about the date, settings and model of camera used to take the picture. RSPython http://www.omegahat.org/RSPython Update to RSPython to handle Long values in Python which is needed for Rexif. gtkDevice http://cran.r-project.org/src/contrib/Descriptions/gtkDevice.html Patch update to remove warning when using a GtkDrawingArea as a device. CGIwithR http://www.omegahat.org/CGIwithR Update to David Firth's CGIwithR package to handle multipart form data and a few additions to the existing features to make them slightly more general.
