This blog is updated daily.
A general description is here.
‘summary.mlm()’ did not handle objects where the formula had been specified by an expression. (Reported by Helios de Rosario Martinez).
‘system()’ and ‘system2()’ when capturing output report a non-zero status in the new ‘"status"’ attribute.
‘assignInNamespace()’ has further restrictions on use apart from at top-level, as its help page has warned. Expect it to be disabled from programmatic use in the future.
‘R CMD INSTALL’ will now do a test load for all sub-architectures for which code was compiled (rather than just the primary sub-architecture).
‘R CMD check’ now gives a warning rather than a note if it finds inefficiently compressed datasets. With ‘bzip2’ and ‘xz’ compression having been available since R 2.10.0, there is no excuse for not using them.
‘summary.mlm()’ did not handle objects where the formula had been
specified by an expression. (Reported by Helios de Rosario Martinez).
‘R CMD check’ now checks line-endings of makefiles and C/C++/Fortran sources in subdirectories of ‘src’ as well as in ‘src’ itself.
It is deprecated to use ‘mean(x)’ and ‘sd(x)’ directly on data frames (or also matrices, for ‘sd’) ‘x’, instead of simply using ‘sapply’.
In the same spirit, ‘median(x)’ now gives an error for a data frame ‘x’ (it often gave nonsensical results).
The ‘Save as’ menu item on the script editor appends ‘.R’ to a file name without an extension.
The ‘Save as’ menu item on the script editor appends ‘.R’ to a file
name without an extension.
‘R CMD INSTALL’ for a package with compiled code will fail if compilation fails for any of the installed sub-architectures: use ‘--no-multiarch’ to override this.
