These consist of:\n\n* **colors and fill patterns** used in various maps to portray quantitative variables with a sequential or diverging pallete, and hatching patterns to convey quantity within a given color\n* **Cheysson fonts** to reflect some character of the hand-drawn style used in these images.\n\nAt present, it is just a work-in-progress, awaiting translation from the original sources\nto R, most likely using the framework of the \n[ggpattern](https://coolbutuseless.github.io/package/ggpattern/) and\n[ggthemes](https://jrnold.github.io/ggthemes/) packages. \nThis README simply documents the sources and steps so far.\n\n### Sources\n\n* David Rumsey acquired the complete set of the _Albums de Statistique Graphique_, and placed\nthem online in the [David Rumsey Map Collection](https://www.davidrumsey.com/luna/servlet/view/search?sort=Pub_List_No_InitialSort%2CPub_Date%2CPub_List_No%2CSeries_No\u0026q=album+de+statistique\u0026search=Go)\n\n* From this, RJ Andrews, [Classic Map Color Design: Recreating palettes from the _Albums de Statistique Graphique._](https://infowetrust.com/project/album-colors), identified 25 maps from the\nAlbums, containing a variety of colors and fill patterns. He then constructed SVG\npatterns in this [Github repo](https://github.com/infowetrust/albumcolors).\n\n* Tom Shanley, [Cheysson Color Palettes](https://observablehq.com/@tomshanley/cheysson-color-palettes). A collection of\nSVG colors and patterns for [Observable](https://observablehq.com).\n\n* Kenneth Fields, [The style of Émile Cheysson](https://www.esri.com/arcgis-blog/products/arcgis-pro/mapping/the-style-of-emile-cheysson/), packages these for [ArcGIS Pro](https://www.esri.com/en-us/arcgis/products/arcgis-pro/overview).\n\n### Colors and fill patterns\n\nThe 25 maps use a variety of sequential, diverging and categorical palettes. These are named\nfor the album year and plate number in  the figure below, for example **1880 map 7** for the\nupper left figure.\n\n\u003cimg src=\"man/figures/maps.png\" width=\"350\"\u003e\n\nRJ Andrews abstracted the color and patterns from these images into SVG files, represented\nin the figure below. He named these according to days of an Advent calendar, \nso, for example, the palette for the image \"1880 map 07\" was published for Advent Day Dec. 06,\nand is labeled \"Dec.06-1880.07\".\n\n\u003cimg src=\"man/figures/RJ-Andrews-color-palettes.jpg\" width=\"600\"\u003e\n\nTom Shanley used these SVG files for his [Cheysson Color Palettes](https://observablehq.com/@tomshanley/cheysson-color-palettes), and unfortunately named\nthem according to RJ's Advent Days. These are contained in the `data-raw/observable/` folder,\nwith names like `dec06.txt`, for the palette of the 1880 Map 7.\n\n\n### Fonts\n\nKenneth Fields created a set of five fonts to mimic the hand drawn lettering used\nin the _Albums_. The reside in the `fonts/` directory as `.ttf` files, and consist of\n`Cheysson Regular`, `Cheysson Italic`, `Cheysson Sans Caps`, `Cheysson Outline Caps`,\nand `Cheysson Title`.\n\n\u003cimg src=\"man/figures/fonts1.png\" width=\"300\"\u003e  \n\u003cimg src=\"man/figures/fonts2.png\" width=\"300\"\u003e\n\n**TODO**: Figure out if these fonts can be installed from the package, or give instructions.\n\n## Installation\n\nThere's not much here yet, but you can install the development version of `ggCheysson` like so:\n\n``` r\nremotes::install.github(\"friendly/ggCheysson\")\n```\n\n## Example\n\nThis is a basic example which illustrates that there's not much that can be done yet.\n\n``` r\nlibrary(ggCheysson)\n## basic example code\n```\n\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffriendly%2Fggcheysson","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffriendly%2Fggcheysson","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffriendly%2Fggcheysson/lists"}
