#' Econodist geom / stat
#'
#' Like [ggplot2::geom_boxplot()] you can either pass in pre-computed
#' values for "ymin", "median", and "ymax" or a single y column
#' which will then use [stat_econodist()] to compute the needed
#' statistics.
#'
#' @param mapping Set of aesthetic mappings created by `aes()` or
#' `aes_()`. If specified and `inherit.aes = TRUE` (the
#' default), it is combined with the default mapping at the top level of the
#' plot. You must supply `mapping` if there is no plot mapping.
#' @param data The data to be displayed in this layer. There are three
#' options:
#'
#' If `NULL`, the default, the data is inherited from the plot
#' data as specified in the call to `ggplot()`.
#'
#' A `data.frame`, or other object, will override the plot
#' data. All objects will be fortified to produce a data frame. See
#' `fortify()` for which variables will be created.
#'
#' A `function` will be called with a single argument,
#' the plot data. The return value must be a `data.frame.`, and
#' will be used as the layer data.
#' @param stat ggplot2 stat to use
#' @param geom ggplot2 geom to use
#' @param position Position adjustment, either as a string, or the result of a call to a position adjustment function.
#' @param tenth_col,median_col,ninetieth_col,median_point_size colors for geom components
#' @param endcap_adjust multipler to make endcaps wider/thinner
#' @param na.rm If `FALSE`, the default, missing values are removed with
#' a warning. If `TRUE`, missing values are silently removed.
#' @param show.legend logical. Should this layer be included in the legends?
#' `NA`, the default, includes if any aesthetics are mapped.
#' `FALSE` never includes, and `TRUE` always includes.
#' It can also be a named logical vector to finely select the aesthetics to
#' display.
#' @param inherit.aes If `FALSE`, overrides the default aesthetics,
#' rather than combining with them. This is most useful for helper functions
#' that define both data and aesthetics and shouldn't inherit behaviour from
#' the default plot specification, e.g. `borders()`.
#' @param ... other arguments passed on to `layer()`. These are
#' often aesthetics, used to set an aesthetic to a fixed value, like
#' `color = "red"` or `size = 3`. They may also be parameters
#' to the paired geom/stat.

Create Diminutive Distribution Charts
## Description
‘The Economist’ has a unique boxplot aesthetic for communicating
distrribution characteristics. Tools are provided to create similar
charts in ‘ggplot2’.
Inspired by:
<https://www.economist.com/united-states/2019/06/29/will-transparent-pricing-make-americas-health-care-cheaper>
## What’s Inside The Tin
- `add_econodist_legend`: Helper utility to get an econodist legend
into a ggplot2 plot
- `econodist_legend_grob`: Create a legend grob that can be used with
econodist charts
- `geom_econodist`: Econodist geom / stat
- `left_align`: Helper to flush ggplot2 plot components to the left
- `mammogram_costs`: Cost of a mammogram in various U.S. Citites
(2016, USD)
- `theme_econodist`: A more current Economist-style ggplot2 theme
The following functions are implemented:
## Installation
``` r
devtools::install_git("https://git.rud.is/hrbrmstr/ggeconodist.git")
# or
devtools::install_git("https://git.sr.ht/~hrbrmstr/ggeconodist")
# or
devtools::install_gitlab("hrbrmstr/ggeconodist")
# or
devtools::install_bitbucket("hrbrmstr/ggeconodist")
```
## Usage
``` r
library(ggeconodist)
# current version
packageVersion("ggeconodist")
## [1] '0.1.0'
```
### The whole shebang
**YOU WILL NEED** to install [these
fonts](https://github.com/economist-components/component-typography) to
use the built-in theme. More on how to do that at some point.

\arguments{
\item{mapping}{Set of aesthetic mappings created by \code{aes()} or
\code{aes_()}. If specified and \code{inherit.aes = TRUE} (the
default), it is combined with the default mapping at the top level of the
plot. You must supply \code{mapping} if there is no plot mapping.}
\item{data}{The data to be displayed in this layer. There are three
options:
If \code{NULL}, the default, the data is inherited from the plot
data as specified in the call to \code{ggplot()}.
A \code{data.frame}, or other object, will override the plot
data. All objects will be fortified to produce a data frame. See
\code{fortify()} for which variables will be created.
A \code{function} will be called with a single argument,
the plot data. The return value must be a \code{data.frame.}, and
will be used as the layer data.}
\item{stat}{ggplot2 stat to use}
\item{position}{Position adjustment, either as a string, or the result of a call to a position adjustment function.}
\item{tenth_col, median_col, ninetieth_col, median_point_size}{colors for geom components}
\item{endcap_adjust}{multipler to make endcaps wider/thinner}
\item{...}{other arguments passed on to \code{layer()}. These are
often aesthetics, used to set an aesthetic to a fixed value, like
\code{color = "red"} or \code{size = 3}. They may also be parameters
to the paired geom/stat.}
\item{na.rm}{If \code{FALSE}, the default, missing values are removed with
a warning. If \code{TRUE}, missing values are silently removed.}
\item{show.legend}{logical. Should this layer be included in the legends?
\code{NA}, the default, includes if any aesthetics are mapped.
\code{FALSE} never includes, and \code{TRUE} always includes.
It can also be a named logical vector to finely select the aesthetics to
display.}
\item{inherit.aes}{If \code{FALSE}, overrides the default aesthetics,
rather than combining with them. This is most useful for helper functions
that define both data and aesthetics and shouldn't inherit behaviour from
the default plot specification, e.g. \code{borders()}.}
\item{geom}{ggplot2 geom to use}
}
\description{
Like \code{\link[ggplot2:geom_boxplot]{ggplot2::geom_boxplot()}} you can either pass in pre-computed
values for "ymin", "median", and "ymax" or a single y column
which will then use \code{\link[=stat_econodist]{stat_econodist()}} to compute the needed
statistics.
