Ensure object has bidirCorrelation slot

Safely upgrades a CoPro/CoProSingle/CoProMulti object created with an older package version (without the bidirCorrelation slot) to the current class definition by recreating an instance of the same class and copying over all available slots. If bidirCorrelation already exists, the object is returned unchanged.

Usage

ensureBidirCorrelationSlot(object)

Arguments

object

A CoProSingle, CoProMulti, or CoProm object

Value

The same object class with a valid bidirCorrelation slot

Examples

# Upgrade legacy object to include bidirCorrelation slot
# obj <- ensureBidirCorrelationSlot(obj)
