I don&#x27;t know why so many people complain about R documentation, I think it&#x27;s pretty good.  The PDFs are useless for sure, but you don&#x27;t have to use that.  Emacs displays documentation pages in a split window.  Or you can use a web browser.<p><a href="https:&#x2F;&#x2F;stat.ethz.ch&#x2F;R-manual&#x2F;R-devel&#x2F;doc&#x2F;html&#x2F;packages.html" rel="nofollow">https:&#x2F;&#x2F;stat.ethz.ch&#x2F;R-manual&#x2F;R-devel&#x2F;doc&#x2F;html&#x2F;packages.html</a>
