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 https://github.com/AtherEnergy/ggTimeSeries)
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
