register_optics {seriation}

Register Seriation Based on OPTICS

Description

Use ordering points to identify the clustering structure (OPTICS) for seriate().

Usage

register_optics()

Details

Registers the method "optics" for seriate(). This method applies the OPTICS ordering algorithm implemented in dbscan::optics() to create an ordering.

Note: Package dbscan needs to be installed.

Value

Nothing.
