This blog is updated daily.
A general description is here.
The ‘NEWS’ files have been re-organized.
This file contains news for R >= 3.0.0: news for the 0.x.y, 1.x.y and 2.x.y releases is in files ‘NEWS.0’, ‘NEWS.1’ and ‘NEWS.2’. The latter files are now installed when R is installed. An HTML version of news from 2.10.0 to 2.15.3 is available as ‘doc/html/NEWS.2.html’.
Methods invoked by ‘NextMethod()’ had a different dynamic parent to the generic. This was causing trouble where S3 methods invoked via lazy evaluation could lose track of their generic. (PR#15267)
‘R CMD check’ does more thorough checking of declared packages and namespaces. It reports
• packages declared in more than one of the ‘Depends’, ‘Imports’, ‘Suggests’ and ‘Enhances’ fields of the ‘DESCRIPTION’ file.
• namespaces declared in ‘Imports’ but not imported from, neither in the ‘NAMESPACE’ file nor using the ‘::’ nor ‘:::’ operators.
• packages which are used in ‘library()’ or ‘requires()’ calls in the R code but were already put on the search path _via_ ‘Depends’.
• packages declared in ‘Depends’ not imported _via_ the ‘NAMESPACE’ file (except the standard packages). Objects used from ‘Depends’ packages should be imported to avoid conflicts and to allow correct operation when the namespace is loaded but not attached.
See ‘Writing R Extensions’ for good practice.
‘mcMap()’ was not exported by package ‘parallel’. (PR#15439)
