In riatelab/mapinsetr: Create Map Insets

Rbind sf Objects With Rows and Cols Handling

Description

Takes a list of sf polygons or multipolygons objects and output a single sf polygon or multipolygon object.

Usage

inset_rbinder(l = list())

Arguments

l	a list of sf POLYGON or MULTIPOLYGON objects.

Value

An sf polygon or multipolygon object is returned.

Examples

library(sf)
nc <- st_read(system.file("shape/nc.shp", package="sf"))
nc <- st_transform(nc, 32119)

plot(st_geometry(nc))
mask1 <- st_buffer(st_centroid(st_geometry(nc[nc$CNTY_ID == 2026,])),dist = 30000)
mask2 <- st_buffer(st_centroid(st_geometry(nc[nc$CNTY_ID == 2016,])),dist = 30000)
plot(st_geometry(mask1), border = "red", lwd = 2, add = TRUE)
plot(st_geometry(mask2), border = "red", lwd = 2, add = TRUE)
inset1 <- move_and_resize(nc, mask1, xy = c(200000, 5000), k = 2)
inset2 <- move_and_resize(nc, mask2, xy = c(200000 + 130000, 5000), k = 2)
plot(st_geometry(inset1), add = TRUE)
plot(st_geometry(inset2), add = TRUE)

nc_insets <- inset_rbinder(l = list(nc, inset1, inset2))
plot(st_geometry(nc_insets))
plot(nc_insets[,9])
