A new release 0.9.8 of
Rcpp
is now on
CRAN and will also get into
Debian shortly (once I finish building R 2.14.1).
This release contains a few incremental changes.
Romain, sponsored by
by the Open Source Programs Office at Google, had released a new
package
int64 bringing
larger integers to
R, and this is now
supported by
Rcpp
as well.
John Chambers contributed some code to have Reference Classes extend existing
C++ classes (typically brought in via Rcpp Modules).
Jelmer Ypma sent us a patch to add a
Rcout device
not unlike cout, but aligned with R's io buffering.
We added some more unit tests, and made a few small fixes here or there.
The complete NEWS entry is below; more details are in the ChangeLog file in the package and on the
Rcpp Changelog page.
0.9.8 2011-12-21
o wrap now handles 64 bit integers (int64_t, uint64_t) and containers
of them, and Rcpp now depends on the int64 package (also on CRAN).
This work has been sponsored by the Google Open Source Programs
Office.
o Added setRcppClass() function to create extended reference classes
with an interface to a C++ class (typically via Rcpp Module) which
can have R-based fields and methods in addition to those from the C++.
o Applied patch by Jelmer Ypma which adds an output stream class
'Rcout' not unlike std::cout, but implemented via Rprintf to
cooperate with R and its output buffering.
o New unit tests for pf(), pnf(), pchisq(), pnchisq() and pcauchy()
o XPtr constructor now checks for corresponding type in SEXP
o Updated vignettes for use with updated highlight package
o Update linking command for older fastLm() example using external
Armadillo
Thanks to
CRANberries, you can also look at a
diff to the previous release 0.9.7.
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
I've come to realize that I quite like coding in cafes, from time to time,
and it can be very productive for me.
This is strange, since I'm usually very sensitive to noise when I work.
Almost any unpredictable sounds at the office distract me,
which is why I often listen to music.
However, in a cafe, I don't need that, I just automatically block out
everything but my laptop.
At the office, everything that happens around
me might concern or interest me.
In a cafe, nobody says anything that I'm interested in.
Another distraction that cafes lack is the Internet.
Even when there's Internet access,
I tend to turn my laptop's wifi off so that I have a longer battery life.
I might occasionally check mail or IRC, but only for a few minutes at a time.
The rest of the time I crank the widget and write code or take care of
other things from my next actions list.
One of my side projects for these last months was to enroll on the online
