||Thinking inside the box|

Turned out I could, and it became a nice evening out. Darren Hanlon started up the evening as the opener for a good half hour, and was quite decent; somewhat charming in a good natured way, not taking himself too too seriously. I'd gladlt see him again.
After a longer-than-needed break Billy Bragg came on stage and played for two straight hours, alternating between an electric and acoustic guitar. And also alternating between some newer material and (especially towards the end and the encore) some old crowd-pleasure. I don't know his material all that well but have of course know of his career over these last 25 years and am quite glad I went to see him. Nice way to end the week.
This release adds quite few things. The main one may be the addition of
density, distribution, quantile and random number functions for a rather large
number of statistical distribution. Usage is pretty much as it would be in R,
yet it is vectorised at the C++ level. A fair number of unit tests were
added too, but some work is left to do there too.
The NEWS entry follows below:
0.8.6 2010-09-09 o new macro RCPP_VERSION and Rcpp_Version to allow conditional compiling based on the version of Rcpp #if defined(RCPP_VERSION) && RCPP_VERSION >= Rcpp_Version(0,8,6) ... #endif o new sugar functions for statistical distributions (d-p-q-r functions) with distributions : unif, norm, gamma, chisq, lnorm, weibull, logis, f, pois, binom, t, beta. o new ctor for Vector taking size and function pointer so that for example NumericVector( 10, norm_rand ) generates a N(0,1) vector of size 10 o added binary operators for complex numbers, as well as sugar support o more sugar math functions: sqrt, log, log10, exp, sin, cos, ... o started new vignette Rcpp-quickref : quick reference guide of Rcpp API (still work in progress) o various patches to comply with solaris/suncc stricter standards o minor enhancements to ConvolutionBenchmark example o simplified src/Makefile to no longer require GNU make; packages using Rcpp still do for the compile-time test of library locations
As always, even fuller details are in 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
