Take a tibble containing population
estimates per year and extend this by copying the latest estimates n

extend_pop_estimates(pops_df, max_pop_year, year_var = "year")
pops_df | a tibble containing population estimates |
---|---|
max_pop_year | The latest year required |
year_var | The variable containing the year |
