This blog is updated daily.
A general description is here.
‘configure’ will find the Sun TI-RPC implementation of xdr (in ‘libtirpc’) provided its header files are in the search path: see the ‘R Installation and Administration Manual’.
In a ‘.Rd’ file, ‘\code{''}’ was mis-converted to latex and rendered in
e.g. PDF as a double quote (a single character).
‘package.skeleton()’ will no longer dump S4 objects supplied directly rather than in a code file. These cannot be restored correctly from the dumped version.
Plotting ‘pch = '.'’ now guarantees at least a one-pixel dot if ‘cex > 0’.
‘findClasses’, ‘getGeneric’, ‘findMethods’ and ‘hasMethods’ are revised to deal consistently with the ‘package=’ argument and be consistent with soft namespace policy for finding objects.
The ‘experimental’ alternative specification of a namespace via ‘.Export()’ etc is now defunct.
The ‘experimental’ alternative specification of a namespace via ‘.Export()’ etc is now deprecated.
The use of ‘.required’ by ‘require()’ and ‘detach()’ has been replaced by ‘.Depends’ which is set from the ‘Depends’ field of a package (even in packages with namespaces). By default ‘detach()’ prevents such dependencies from being detached: this can be overridden by the argument ‘force’.
S4 methods are uncached whenever the namespace containing them is unloaded (by ‘unloadNamespace()’ as well as by ‘detach(unload = TRUE))’.
‘help()’ has a new argument ‘help_type’ (with default set by the option of that name) to supersede arguments ‘offline’, ‘htmlhelp’ and ‘chmhelp’ (although for now they still work if ‘help_type’ is unset). There is a new type, ‘"PDF"’ to allow offline PDF (rather than PostScript).
A function ‘offline_help_helper()’ will be used if this exists in the workspace or further down the search path, otherwise the function of that name in the ‘utils’ namespace is used.
