<p></p>
<p>Time for another update of <a href="http://dirk.eddelbuettel.com/code/rcpp.armadillo.html">RcppArmadillo</a> with a new release 0.7.700.0.0 based on a fresh <a href="http://arma.sourceforge.net/">Armadillo</a> 7.700.0. Following my full reverse-dependency check of 318 package (<a href="https://github.com/RcppCore/rcpp-logs/commit/22a6515ef80b264e40578e7fbbc15a490412dcc3">commit of log here</a>), <a href="https://cran.r-project.org/">CRAN</a> took another day to check again.</p>
<p><a href="http://arma.sourceforge.net/">Armadillo</a> is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. <a href="http://dirk.eddelbuettel.com/code/rcpp.armadillo.html">RcppArmadillo</a> integrates this library with the <a href="https://www.r-project.org/">R</a> environment and language--and is widely used by (currently) 318 other packages on <a href="https://cran.r-project.org/">CRAN</a> -- an increase of 20 just since the last <a href="https://cran.r-project.org/">CRAN</a> release of 0.7.600.1.0 in December!</p>
<p>Changes in this release relative to the previous <a href="http://cran.r-project.org/">CRAN</a> release are as follows:</p>
