<p>A new release of <a target="_blank" rel="nofollow" href="http://dirk.eddelbuettel.com/code/rcpp.toml.html">RcppTOML</a> is now on <a target="_blank" rel="nofollow" href="https://cran.r-project.org/">CRAN</a>. This release fixes a few parsing issues for less frequently-used inputs: vectors of boolean or date(time) types, as well as table array input.</p>
<p><a target="_blank" rel="nofollow" href="http://dirk.eddelbuettel.com/code/rcpp.toml.html">RcppTOML</a> brings <a target="_blank" rel="nofollow" href="https://github.com/toml-lang/toml">TOML</a> to R. <a target="_blank" rel="nofollow" href="https://github.com/toml-lang/toml">TOML</a> is a file format that is most suitable for configurations, as it is meant to be <em>edited by humans</em> but read by computers. It emphasizes <em>strong readability for humans</em> while at the same time supporting <em>strong typing</em> as well as <em>immediate and clear error reports</em>. On small typos you get parse errors, rather than silently corrupted garbage. Much preferable to any and all of XML, JSON or YAML — though sadly these may be too ubiquitous now. <a target="_blank" rel="nofollow" href="https://github.com/toml-lang/toml">TOML</a> is making good inroads with newer and more flexible projects such as the <a target="_blank" rel="nofollow" href="https://gohugo.io/">Hugo</a> static blog compiler, or the <a target="_blank" rel="nofollow" href="https://crates.io/">Cargo</a> system of Crates (aka &quot;packages&quot;) for the <a target="_blank" rel="nofollow" href="https://www.rust-lang.org/en-US/">Rust language</a>.</p>
<blockquote>

<p>The README.md file was expanded with an example and screenshot.</p>
