`ggalt` : Extra Geoms, Stats and Coords for `ggplot2`
A package containing additional geoms, coords and stats for the revamped (late 2015) version
of ggplot2.
8 years ago
The first three forays into this brave, new `ggplot2` world are _splines_! and being able to use the (much better) `KernSmooth::bkde` and `KernSmooth::bkde2D` for density plots.

*NOTE*
Until the new `ggplot2` version is on CRAN, you'll need to install it from github (see below).
The following functions are implemented:
- `geom_xspline` : Connect control points/observations with an X-spline
- `stat_xspline` : Connect control points/observations with an X-spline
- `geom_bkde` : Display a smooth density estimate (uses `KernSmooth::bkde`)
- `stat_bkde` : Display a smooth density estimate (uses `KernSmooth::bkde`)
8 years ago
- `geom_bkde2d` : Contours from a 2d density estimate. (uses `KernSmooth::bkde2D`)
- `stat_bkde2d` : Contours from a 2d density estimate. (uses `KernSmooth::bkde2D`)
