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 tText and latex help, eventually also and the the run-nable 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; but almost all errors in packages are previously undetected/corrected errors in the package sources or changes in the Rd dialect..
"\uxxxx" and "\Uxxxxxxxx" escapes can now be parsed to a UTF-8 encoded string even in non-UTF-8 locales (this has been implemented on Windows since R 2.7.0). (Use of such escapes requires MBCS support.)
Outlier symbols drawn by boxplot() now obey the 'outlwd' argument. Reported by Jürgen Kluge.
parse_Rd() no longer includes the newline as part of a "%"-style comment.
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.
