sector_gap(df, metric_col, year_col = "end_year")

Arguments

df

Dataframe with charter sector and district rows, including is_charter_sector, is_district, and is_allpublic flags

metric_col

Character. Performance metric column.

year_col

Character. Year column. Default "end_year".

Value

Dataframe with one row per city-year containing:

  • charter_value: Charter sector metric value

  • district_value: Traditional district metric value

  • sector_gap: charter_value - district_value

  • sector_leader: "charter", "district", or "tie"

Examples

if (FALSE) { # \dontrun{
# Get sector gaps for all host cities
grate_with_aggs %>%
  sector_gap(metric_col = "grad_rate")
} # }
