Now that Rcpp 0.9.10 is released and on CRAN, other packages can take advantage of a small change needed to make use of the quasi-output stream Rcpp::Rcout. So the new release 0.2.35 of RcppArmadillo does just that—and input/output from Armadillo, the wonderful linear algebra / math library for C++ written chiefly by Conrad Sanderson now comes through in a coordinated buffered fashion. As as std::cout is no longer used by default, the R CMD check no longer flags this.

There are two more bugfixes in the releases for issues noticed by attentive RcppArmadillo users. Teo Guo Ci spotted a missing semicolon when C++0x code was activated, and Gershon Bialer suggested a fix for an issue plagueing users of the jurassic g++ 4.2.1 compiler which Apple forces on users of OS X. We thank Martin Renner for testing these fixes. The NEWS entry below summarises the changes.

0.2.35  2012-02-17

    o   Upgraded to Armadillo release 2.4.3

          * Support for ARMA_DEFAULT_OSTREAM using Rcpp::Rcout added

    o   Minor bug fix release improving corner cases affecting builds:

          * Missing semicolon added in Mat_meat (when in C++0x mode), with
            thanks to Teo Guo Ci 
          * Armadillo version vars now instantiated in RcppArmadillo.cpp
            which helps older g++ versions, with thanks to Gershon Bialer
          * Thanks also to Martin Renner for testing these changes

          * Unit tests output fallback directory changed per Brian Ripley's
            request to not ever use /tmp

          * Minor update to version numbers in RcppArmadillo-package.Rd

Courtesy of CRANberries, there is also a diffstat reports for 0.2.35 relative to 0.2.34 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.
