RcppArmadillo 0.3.2.0

A new stable release 3.2.0 of Armadillo is now available. As usual, we have wrapped this into a new RcppArmadillo package, now at 0.3.0.2; and this version is now available via CRAN.

The short NEWS entry follows below. For those interested in following RcppArmadillo eevn more closely, we generally track Conrad's Armadillo release candidates as well in SVN on R-Forge but do no longer submit these to CRAN (as the CRAN maintainers have enough incoming packages).

0.3.2.0  2012-05-21

    o   Upgraded to Armadillo release 3.2.0 "Creamfields"

          * faster eigen decomposition via "divide and conquer" algorithm
          * faster transpose of vectors and compound expressions
          * faster handling of diagonal views
          * faster handling of tiny fixed size vectors (≤ 4 elements)
          * added unique(), for finding unique elements of a matrix

Courtesy of CRANberries, there is also a diffstat report for 0.3.2.0 relative to 0.3.0.3 As always, more detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.
