Description

Usage

Arguments

x	An 'sf' object with CRS EPSG:4674. Usually an object returned from other geobr functions, such as read_country(), read_states(), read_municipality(), or similar functions.

Value

An sf data frame with the same attributes as x, but with distant islands removed from the geometry.

Examples

library(geobr)
library(sf)

br <- read_country(year = 1991)

br_no_islands <- remove_islands(br)

plot(br)
