`ggalt` : Extra Coordinate Systems, Geoms, Statistical Transformations, Scales & Fonts for 'ggplot2'
A compendium of 'geoms', 'coords', 'stats', scales and fonts for 'ggplot2', including splines, 1d and 2d densities, univariate average shifted histograms, a new map coordinate system based on the 'PROJ.4'-library and the 'StateFace' open source font 'ProPublica'.
The following functions are implemented:
- `geom_ubar` : Uniform width bar charts
- `geom_horizon` : Horizon charts (modified from )
- `coord_proj` : Like `coord_map`, only better (prbly shld use this with `geom_cartogram` as `geom_map`'s new defaults are ugh)
- `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`)
- `geom_stateface`: Use ProPublica's StateFace font in ggplot2 plots
- `geom_bkde2d` : Contours from a 2d density estimate. (uses `KernSmooth::bkde2D`)
- `stat_bkde` : Display a smooth density estimate (uses `KernSmooth::bkde`)
- `stat_bkde2d` : Contours from a 2d density estimate. (uses `KernSmooth::bkde2D`)
- `stat_ash` : Compute and display a univariate averaged shifted histogram (polynomial kernel) (uses `ash::ash1`/`ash::bin1`)
- `geom_encircle`: Automatically enclose points in a polygon
- `byte_format`: + helpers. e.g. turn `10000` into `10 Kb`
- `geom_lollipop()`: Dead easy lollipops (horizontal or vertical)
- `geom_dumbbell()` : Dead easy dumbbell plots
- `stat_stepribbon()` : Step ribbons
- `annotation_ticks()` : Add minor ticks to identity, exp(1) and exp(10) axis scales independently of each other.
- `geom_spikelines()` : Instead of geom_vline and geom_hline a pair of segments that originate from same c(x,y) are drawn to the respective axes.
- plotly integration for a few of the ^^ geoms
