Please join us for our inaugural talk by Dr. Heike Hofmann from the Department of Statistics at the University of Nebraska-Lincoln.

**Extensions to ggplot2 are easy – right?**
*Writing an extension to ggplot2 for your own custom chart is a way to leverage the full force of ggplot2:*
*you are linking your chart into the grammar of graphics; things like legends, adding additional layers or making small multiples by faceting along other variables just ‘work out of the box’.*
*On top of that, you are signalling to the large crowd of ggplot2 users that your plot will play nicely with their plots.*
*… or so things would be in an ideal world.*
*We will discuss some of the pitfalls we encountered when writing ggplot2 extensions across different packages: some of which have made it onto CRAN, some are even listed as ggplot2 extension packages, … and some are not.*
*If you have worked with ggplot2 before, and have at times thought that you would like move your specialty chart into a ggplot2 extension, I’d encourage you to come!*
*You should get a pretty good idea of how to approach writing a ggplot2 extension and where things might get tricky. Bring your laptop and try things out during the talk!*

**Location**
We will meet in the Arbor Suite at the University of Nebraska's **[East Campus Union](https://maps.unl.edu/NEU)** (1705 Arbor Drive, Lincoln, NE 68503). There is [metered parking](https://parking.unl.edu/maps/VisitorGuestParkingEastCampus.pdf) in the lot just north of the union.
