hershey package contains the Hershey vector fonts in a number of formats for more convenient use within Rstats.
The Hershey fonts were developed in the 1960s. Each glyph is defined as collections of staight line segments - hand calculated by Hershey by sketching them on grid paper!
This package makes available the coordinates of the stroke endpoints for every glyph.
You may need this package if:
You can install the development version from GitHub with:
hershey_raw: the original encoding for every glyph (See the vignette for how to parse).
hershey: a data.frame of the vector strokes for every glyph.
hershey_svg: a list of SVG paths for every glyph.
The following are examples of the representation of the letter

create_string_df() will create a data.frame of all the characters in the given string. It will offset each character by the known widths of the preceding characters to create a well-spaced set of points.
Totally free (except if you convert them to the proprietary US NTIS format)
USE RESTRICTION: This distribution of the Hershey Fonts may be used by anyone for any purpose, commercial or otherwise, providing that: 1. The following acknowledgements must be distributed with the font data: - The Hershey Fonts were originally created by Dr. A. V. Hershey while working at the U. S. National Bureau of Standards. - The format of the Font data in this distribution was originally created by James Hurt Cognition, Inc. 900 Technology Park Drive Billerica, MA 01821 (mit-eddie!ci-dandelion!hurt) 2. The font data in this distribution may be converted into any other format *EXCEPT* the format distributed by the U.S. NTIS (which organization holds the rights to the distribution and use of the font data in that particular format). Not that anybody would really *want* to use their format... each point is described in eight bytes as "xxx yyy:", where xxx and yyy are the coordinate values as ASCII numbers.
