R Documentation

An S4 class to represent the `ecdattr` row in the Elliptic Database (ECDB)

Description

The ecdattr class serves as an object-oriented interface between R and ECDB. This class is used extensively during the bootstrap process. A list of light-weight ecdattr objects is created first by ecdattr.pairs function, then the ecdattr.enrich function is invoked in parallel to calculate additional ecd attributes.
