This blog is updated daily..
A general description is here.
Package help is now converted from Rd by the R-based converters that were first introduced in 2.9.0. This means
- Packages that were installed by R-devel after 2009-08-09 should not be used with earlier versions of R, and some aspects of package help will be missing if there are so used. (Currently text and latex help, eventually also the run-able examples.)
- Text help, latex help and examples for packages installed under the new system is converted on-demand from stored parsed Rd files. (Conversions stored in earlier installations are still used.)
The converters are still being polished and produce incorrect latex or HTML conersions for ca 20 packages. However, they correct fewer errors in the inputs and most errors seen have been the result of errors in package sources; but almost all errors in packages are previously undetected/corrected errors in the package sources or changes in the Rd dialect..
DESCRIPTION 'LinkingTo' specs are now recognized as installation dependencies, and included in package management computations.
Standardized DESCRIPTION 'License' specs are now available for package management computations.
Outlier symbols drawn by boxplot() now obey the 'outlwd' argument. Reported by Jürgen Kluge.
srcref records produced by parse() and parse_Rd() did not record the encoding of the source file. (Reported by Romain François.)
gregexpr() no longer segfaults when "" is given as the search pattern. Thanks to Hervé Pagès for the bug report.
CHAR() now returns (const char *) since CHARSXPs should no longer be modified in place. This change allows compilers to warn or error about improper modification. Thanks to Hervé Pagès for the suggestion.
