(This article was first published on <strong><a href="http://dirk.eddelbuettel.com/blog/2018/11/24#rcppeigen_0.3.3.5.0"> Thinking inside the box </a></strong>, and kindly contributed to <a rel="nofollow" href="https://www.r-bloggers.com/">R-bloggers)</a> </div>
<p>Another minor release 0.3.3.5.0 of <a rel="nofollow" href="https://cran.r-project.org/package=RcppEigen" target="_blank">RcppEigen</a> arrived on <a rel="nofollow" href="https://cran.r-project.org/" target="_blank">CRAN</a> today (and just went to <a rel="nofollow" href="https://www.debian.org/" target="_blank">Debian</a> too) bringing support for <a rel="nofollow" href="http://eigen.tuxfamily.org/" target="_blank">Eigen</a> 3.3.5 to R.</p>
<p>As we now carry our small set of patches to <a rel="nofollow" href="http://eigen.tuxfamily.org/" target="_blank">Eigen</a> as <code>diff</code> in our repo, it was fairly straightforward to bring <a rel="nofollow" href="https://github.com/RcppCore/RcppEigen/blob/master/patches/eigen-3.3.5.diff" target="_blank">these few changes</a> to the new upstream version. I added one trivial fix of changing a return value to <code>void</code> as this is also already in the upstream repo. Other than that, we were fortunate to get two nice and focussed PRs since the last release. Ralf allowed us to use larger index values by using <code>R_xlen_t</code>, and Michael corrected use of RcppArmadillo in a benchmarking example script.</p>
<p>Next, it bears repeating what we said <a rel="nofollow" href="http://dirk.eddelbuettel.com/blog/2018/02/07#rcppeigen_0.3.3.4.0" target="_blank">in February when we release 0.3.3.4.0</a>:</p>
<blockquote>
<p>One additional and recent change was the accomodation of a recent CRAN Policy change to not allow <code>gcc</code> or <code>clang</code> to mess with diagnostic messages. A word of caution: this may make your compilation of packages uses <a rel="nofollow" href="https://cran.r-project.org/package=RcppEigen" target="_blank">RcppEigen</a> very noisy so consider adding <code>-Wno-ignored-attributes</code> to the compiler flags added in your <code>~/.R/Makevars</code>.</p>
</blockquote>
<p>It’s still super-noise, but hey, <a rel="nofollow" href="https://cran.r-project.org/" target="_blank">CRAN</a> made us do it …</p>
<p>The complete <code>NEWS</code> file entry follows.</p>
