Filter Dataset by Geographic Region and Time Period — region_period

Enhances and filters a repository dataset based on specified geographic regions and a defined time window. Regional information is added by merging with an external country-to-region mapping file.

region_period_filter(
  repo,
  geo = c("Africa-E", "Africa-W", "Americas", "Asia-Pacific", NA),
  year_min = -Inf,
  year_max = +Inf
)

Arguments

repo: A `data.frame` or tibble containing the input dataset. Must include a `country` column.
geo: Character vector of region names to retain. Defaults to common WHO-defined macro-regions: `"Africa-E"`, `"Africa-W"`, `"Americas"`, `"Asia-Pacific"`, and `NA`.
year_min: Integer or numeric. Minimum year to include (inclusive). Defaults to `-Inf` (no lower bound).
year_max: Integer or numeric. Maximum year to include (inclusive). Defaults to `Inf` (no upper bound).

Value

A filtered dataframe including only rows matching the selected region(s) and within the defined time period.
