.makeWide {bsynth}

Convert Data to Wide Format

Description

This internal helper function transforms data from a long format, where each row represents an observation for a specific unit and time, to a wide format, where each row represents a time period and each column represents a unit's outcome. It specifically focuses on separating treated and untreated units.
