Two exciting upcoming talks:

Smooth curves in R by Niels Lundtorp Olsen

R is a great and flexible software but lacks an easy and fast package for dealing curves such as in functional data and vector graphics.
This talk will not be about all the cool tools for making plots, but we will go one step behind and look at how smooth curves are represented as data in a computer, and how to implement this in R.
Doing things fast in R often means doing it in C++, which also will bring us past object-oriented programming. In the end, we get a package that can easily be applied to functional data and elsewhere. This is work in progress and feedback will be appreciated.

Xaringan shenanigans by Claus Thorn Ekstrøm

R provides several possibilities for using Rmarkdown to quickly create
excellent presentations combining R code, R output, mathematics,
animations, and interactive widgets.

In this code-along I will show how to use the package xaringan to
build simple, elegant, Rmarkdown-driven presentations based on the
remark.js presentation framework. We will cover formatting, widgets,
caveats, show some tips and tricks, and how to customise your own
presentation template.
