metapost-package {metapost}

R Interface to MetaPost

Description

Provides an R interface to METAPOST. There are functions to generate an R description of a MetaPost curve, functions to generate MetaPost code from an R description, functions to process MetaPost code, and functions to read solved MetaPost paths back into R.

Details

Generate a MetaPost path with functions like knot.

Write the MetaPost path to a file with metapost.

Run mpost on the file with mpost.

Read the solved path (Bezier control points) into R with mptrace.

Draw a solved path with grid.metapost.

It is also possible to pass grid.metapost the original path (and it will perform the write/solve/read steps itself).
