## Not run: 
data(clea_deu2009)
out_1 <- update_bbox(clea_deu2009[clea_deu2009$cst_n%in%c("Berlin"),])
out_1

# Bounding box of full dataset
data.table::as.data.table(clea_deu2009)[,sf::st_bbox(geometry)]

# Bounding box of subset (incorrect)
data.table::as.data.table(clea_deu2009)[cst_n%in%c("Berlin"),sf::st_bbox(geometry)]

# Corrected bounding box
data.table::as.data.table(out_1)[,sf::st_bbox(geometry)]
