# ggeconodist

Create Diminutive Distribution Charts

## Description

‘The Economist’ has a unique boxplot aesthetic f or 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
install.packages("ggeconodist", repos = "https://cinc.rud.is")
# or
remotes::install_git("https://git.rud.is/hrbrmstr/ggeconodist.git")
# or
remotes::install_git("https://git.sr.ht/~hrbrmstr/ggeconodist")
# or
remotes::install_gitlab("hrbrmstr/ggeconodist")
# or
remotes::install_bitbucket("hrbrmstr/ggeconodist")
# or
remotes::install_github("hrbrmstr/ggeconodist")
```

NOTE: To use the ‘remotes’ install options you will need to have the
[{remotes} package](https://github.com/r-lib/remotes) installed.

## 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.
