An Interface to the 'Ravelry' API.

ravelRy

ravelRy is an R package that provides access to the Ravelry API.

Ravelry describes itself as a place for knitters, crocheters, designers, spinners, weavers and dyers to keep track of their yarn, tools, project and pattern information, and look to others for ideas and inspiration.
