Create sf objects from coordinates

These are simple wrapper functions for creating sf objects from points

Usage

sf_line(..., crs = 4326)

sf_point(..., crs = 4326)

sf_points(..., crs = 4326)

sf_polygon(..., crs = 4326)

sf_box(xmin, ymin, xmax, ymax, crs = 4326)

Arguments

...

The coordinates of the object

crs

The coordinate reference system. Defaults to 4326

xmin, xmax, ymin, ymax

Corners for sf_box

Value

An sf object of the appropriate type

Examples

pt_a <- c(-90, 45)
pt_b <- c(-89, 44)
pt <- sf_points(pt_a)
line <- sf_line(pt_a, pt_b)
