<p>Last week, I gave an overview of bunch of tidyverse packages (tibble, dplyr, tidyr, ggplot, readr, purrr) to the <a target="_blank" href="https://d-rug.github.io/">Davis R-Users’ Group</a>. Here is that talk (and since videos don’t display everywhere this blog is syndicated, <a target="_blank" href="https://www.youtube.com/watch?v=9q7gssUP8UA">here is the YouTube link</a>).</p>
<p>I mention early in the talk that the <code>github_markdown</code> specification in the YAML header produces a conveniently GitHub-renderable markdown file – <a target="_blank" href="https://github.com/michaellevy/tidyverse_talk/blob/master/tidyverse.md">here that is if you’d like to follow along</a>, or you can download the <a target="_blank" href="https://github.com/michaellevy/tidyverse_talk/blob/master/tidyverse.nb.html">rendered R Notebook (nb.html) file</a>, which itself includes the R Markdown file (Awesome! In the upper right of the html file, click “Code” -> “Download Rmd”).</p>

<p>One final note, on the speed of tidyverse functions. Some tidyverse functions really do offer a speed advantage over base R (e.g. <code>read_csv</code> and <code>filter</code>), but the <code>map</code> speed advantage I mention here over <code>lapply</code> seems to be an artifact of both being wrapped in a <code>map2</code> call in a <code>data_frame</code> call. They are actually equally fast. In my mind, the benefit of the tidyverse is that it makes R easier to write and read, which makes it less bug-prone and more approachable for beginners. It does that without imposing a speed penalty, and in some cases provides a little acceleration as a bonus.</p>
