R Project Updates
Updates from R Core.
-
source()
gets new optional arguments, notablyexprs
; this is made use of in the new utility functionwithAutoprint()
. -
print.factor()
no longer sets the class of the factor toNULL
, which would violate a basic constraint of an S4 object. -
There was an exception for the native Solaris C++ compiler to the dropping (in R 3.3.0) of legacy C++ headers from headers such as
R.h
andRmath.h
- this has now been removed. That compiler has strict C++98 compliance hence does not include extensions in its (non-legacy) C++ headers: some packages will need to request C++11 or replace non-C++98 calls such aslgamma
: see §1.6.4 ofWriting R Extensions
. -
sys.source()
gets a newtoplevel.env
argument. This argument is useful for frameworks running package tests. -
c()
’s argumentuse.names
is documented now, as belonging to the (C internal) default method. In “parallel”, argumentrecursive
is also moved from the generic to the default method, such that the formal argument list ofbase
genericc()
is just(...)
. -
If available, the POSIX 2008 system call
utimensat
will be used bysetFileTime()
andfile.copy()
. This may result in slightly more accurate file times. -
Sys.setFileTime()
andfile.copy(copy.date = TRUE)
will set timestamps with fractions of seconds on platforms/filesystems which support this. -

will be used bysetFileTime()
andfile.copy()

The online documentation for package
methods
is extensively rewritten. The goals are to simplify documentation for basic use, to note old features not recommended and to correct out-of-date information. -
Calls to
setMethod()
no longer print a message when creating a generic function in those cases where that is natural: S3 generics and primitives. -
Use
options(deparse.max.lines=)
to limit the number of lines recorded in.Traceback
and other deparsing activities. -
abbreviate()
gains an optionnamed = TRUE
. -
Installation support for
readline
emulations based oneditline
(akalibedit
) is deprecated. -
Convenience function
hasName()
has been added; it is intended to replace the common idiom!is.null(x$name)
without the usually unintended partial name matching. -
split(<very_long>, *)
now works with long vectors. -
The license check enabled by
options(checkPackageLicense = TRUE)
is now done when the package’s namespace is first loaded. -
citation()
supportsinst/CITATION
files from package source trees, withlib.loc
pointing to the directory containing the package. -
(Windows only) Function
setInternet2()
is defunct. -
(Windows only)
file.info()
now returns file timestamps including fractions of seconds; it has done so on other systems since R 2.14.0.
Upcoming Events
- eRum 2016 Poznan, Poland 12 October - 14 October
European R users meeting (eRum) is an international conference that aims at integrating users of the R language. eRum 2016 will be a good chance to exchange experiences, broaden knowledge on R and collaborate.
Quote of the Week
I really enjoyed the #Rstats meetup last night. Hadley says he's going to do so many packages. Why hasn't he done them in the last 30 years?
