Source: R/panel_gaps.R

gap_summary() reports how many time periods are missing for each panel unit.

Usage

gap_summary(data, id, time)

Arguments

data

A data frame or tibble.

id

Unquoted column name identifying the panel unit.

time

Unquoted column name identifying the time period.

Value

A tibble with one row per panel unit and a column panelbuild_missing_periods giving the number of missing time periods for that unit. If no gaps are present, all units are returned with zero missing periods.

Details

This function summarizes the missing unit-time cells returned by panel_gaps() at the panel-unit level. It is useful for identifying which units contribute most to panel imbalance.

The function does not modify, complete, or impute the input data.
