ggplot2 extension package: ggforce - accelerating ggplot2

[Thomas]

Following the release of ggplot2 v2.0.0 I've started a package, ggforce, for collecting extensions to ggplot2 in the form of new geoms, stats, positions etc. While I do not believe there need to be single source of ggplot2 extension, if you've developed an extension but do not wish to commit to maintaining a package I am very welcoming to pull requests as well as well described feature requests.

The package is in its infancy and only on github (https://github.com/thomasp85/ggforce) at the moment (CRAN release will happen once it includes more extensions). Currently it includes:

• geom_arc/stat_arc for drawing circle segments
• geom_edge_bundles / stat_edge_bundles for drawing hierarchical edge bundles
• power_trans for creating power transformations
• trans_reverser for reversing any transformation (flipping direction)
• radial_trans for transforming between radial and cartesian coordinates

The github page contains a list of pending extensions that will (hopefully) be developed.

with best wishes and happy new year
