Announcing curry: Operator based currying and partial application
I am pleased to announce the release of curry – a small package I’ve developed as part of improving my meta-programming skills. curry is yet another attempt at providing a native currying/partial application mechanism in R. Other examples of implementations of this can be found in purrr and functional (and probably others). curry sets i...

Data Driven Logo Design with ggraph and gtable
After having “succesfully” launched my blog I felt the time had come to create some identity for it (and by extension, me). What better way to do this than create a logo? This thought didn’t suddenly appear in my mind – if you’ve read the announcement post you will now that such details have been rummaging around my head for as long a...

Creating a Bees and Bombs gif in R
I love the work of @beesandbombs and while some of his creations are a poor fit for redoing in R, one of his latest got me wondering how I would recreate it in the venerable statistics language… The gif in question can be seen here (I don’t know to make those fancy tweet cards using jekyll and GitHub pages). While it would be nice if this wa...

Becoming The Intern
I was not always this famous… And with this I mean that a year ago only my colleagues knew I did stuff in R and now I’m reaching a slightly wider audience. Some of this is definitely due to me interning for Hadley Wickham and helping prepare the next release of ggplot2. In fact I think it’s a fair bet that if you’re reading this it is due...

Announcing ggforce: Accelerating ggplot2
I am very pleased to announce the first release of the ggforce package. ggforce is a general ggplot2 extension package in the same vein as ggalt with no overarching goal other than to provide additional functionality to the ggplot2 universe. The inception and birth of ggforce was documented in a recent post and the road to CRAN has been long...

Data Driven Christmas Card Animation with Voronoi Tiles
I recently published a bit of self-promotion in the form of an animation based on the new geom_voronoi_tile() and geom_voronoi_segment() functions in ggforce: Selfpromoting fun with geom_voronoi_* in #ggforce #ggplot2 #tweenr pic.twitter.com/CcFCJ8UDyy— Thomas Lin Pedersen (@thomasp85) December 16, 2016 This prompted someone to ask for the sou...

Introduction to ggraph: Nodes
This is the second post in my series of ggraph introductions. The first post introduced the concept of layouts, which is simply a specification on how nodes should be placed on a plane. This post will dive into how the nodes are drawn, once a layout has been calculated. Nodes Nodes in a network are the entities that are connected. Sometimes the...

Introduction to ggraph: Layouts
I will soon submit ggraph to CRAN – I swear! But in the meantime I’ve decided to build up anticipation for the great event by publishing a range of blog posts describing the central parts of ggraph: Layouts, Nodes, Edges, and Connections. All of these posts will be included with ggraph as vignettes — potentially in slightly ...

Introduction to ggraph: Edges
This is the third post in my series of ggraph introductions. The first post introduced the concept of layouts, which is simply a specification on how nodes should be placed on a plane. The second explained how to draw nodes using the geom_node_*() family. This post will connect the dots, so to speak, by introducing the concept of edges. Edges I...

Announcing ggraph: A grammar of graphics for relational data
I am absolutely thrilled to announce that ggraph has finally been released on CRAN. ggraph is my most ambitious package to date and its very early genesis has been described in a prior post. If any mention of ggraph is completely new to you, then in short terms ggraph is an extension of the ggplot2 API to support relational data such as networks...
