The release fixes a number of bugs that have come up since the
0.11.0 release in January,
but also brings some extensions. See the NEWS file section below for details,
or the ChangeLog file in the package and on the
Rcpp Changelog page
Once again, we tested this release by building against all
which depend upon Rcpp.
In short, three packages are blacklisted from tests, and three came up with
something we noted — but the remaining 177 packages all build and test
cleanly. Detailed results of those tests (and the scripts for it) are on GitHub.
There are a number of other fixes, upgrades and other extensions detailed in
NEWS file extract below, in the ChangeLog file in the package and on the
Rcpp Changelog page.
Changes in Rcpp version 0.11.1 (2014-03-13)
Changes in Rcpp API:
Preserve backwards compatibility with Rcpp
0.10.* by allowing
RObjectextraction from vectors (or lists) of Rcpp objects
Add missing default constructor to Reference class that was omitted in the header-only rewrite
NaNhandling of the
IndexHashclass, as well as the vector
method. These fixes ensure that sugar functions depending on
match()) will now properly handle
values for numeric vectors.
DataFrame::nrowsnow more accurately mimics R’s
internal behavior (checks the row.names attribute)
Numerous changes to permit compilation on the Solaris OS
Rcpp vectors gain a subsetting method – it is now possible to subset an Rcpp vector
CharacterVectors (subset a by name),
LogicalVectors (logical subsetting), and
IntegerVectors (0-based index subsetting). Such subsetting
will also work with Rcpp sugar expressions, enabling expressions
x[ x > 0].
Comma initialization (e.g.
CharacterVector x = "a", "b", "c";, has been disabled, as
it causes problems with the behavior of the
Rcpp::Lists. Users who want to re-enable this functionality
#define RCPP_COMMA_INITIALIZATION, but be aware of
the above caveat. The more verbose
CharacterVector x = CharacterVector::create("a", "b", "c")
Changes in Rcpp Attributes
Fix issue preventing packages with
Rcpp::interfacesattribute from compiling.
Fix behavior with attributes parsing of
arguments, and also allow constructors of a given size
NumericVector v = NumericVector(10))gives a default
numeric(10)at the R level). Also make NAs preserve
type when exported to R (e.g.
NA_STRINGas a default argument
NA_character_at the R level)
Changes in Rcpp modules
CRANberries, you can also look at a
diff to the previous release.
As always, even fuller details are on the
Rcpp Changelog page and the
Rcpp page which also
leads to the downloads, the
browseable doxygen docs
and zip files of doxygen output for the standard formats.
A local directory has source and documentation too.
Questions, comments etc should go to the
rcpp-devel mailing list
off the R-Forge page
