Strategy for dealing with mid-year sessions

Description

Remove or map mid-year session records to full-year sessions according to a chosen algorithm. Operations are performed per participant on data prepared by prepare_data_sdsu().

Usage

map_mid_years(data, algo = NULL)

Arguments

data

tibble. A dataframe produced by prepare_data_sdsu().

algo

character. Mapping algorithm to apply to mid‑year sessions. Allowed values: "next_existing_fy": assign a mid year to the next existing full year. If a participant ends with mid‑year visits, those terminal mid‑year records are dropped. "next_potential_fy": assign a mid year to the next existing full year when present, otherwise assign to the next forecasted full year (that may never materialize). "next_immediate_fy": assign a mid year to the next full year regardless of whether that full year record exists or not. "remove_my": drop mid-year events and keep only full-year events. If NULL (default) no mapping is performed and data is returned unchanged.

Value

tibble. A tibble with session_id remapped or rows filtered.

Examples

## Not run: 
map_mid_years(data, algo = "next_immediate_fy")

## End(Not run)
