RcppArmadillo 0.3.810.0

A new Armadillo release 3.810.0 by Conrad appeared yesterday, and was wrapped up in a new release 0.3.810.0 of RcppArmadillo. Upstream changes bring FFT support as well as more Sparse matrix constructors, and we have an improvement to the sample() function contributed by Christian Gunning.

As RcppArmadillo is used by an increasing number of packages---on CRAN alone, we find 34 direct dependencies---I also added the package to Debian and upload there in parallel.

The summary of the main changes follows:

Changes in RcppArmadillo version 0.3.810.0 (2013-04-19)

• Upgraded to Armadillo release Version 3.810.0 (Newell Highway)

  • added fast Fourier transform: fft()

  • added handling of .imbue() and .transform() by submatrices and subcubes

  • added batch insertion constructors for sparse matrices

  • minor fix for multiplication of complex sparse matrices

• Updated sample() function and test again contributed by Christian Gunning

Courtesy of CRANberries, there is also a diffstat report for the most recent release 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.
