Create bounding box polygon

This function creates a bounding box polygon from it's corner coordinates, setting the coordinate reference system from the supplied EPSG value.

create_bounding_box(xmin, ymin, xmax, ymax, epsg_number)

Arguments

xmin	The left corners easting coordinate as an integer or double.
ymin	The lower corners northing coordinate as an integer or double.
xmax	The right corners easting coordinate as an integer or double.
ymax	The upper corners northing coordinate as an integer or double.
epsg_number	EPSG number as an integer.

Value

The bounding box polygon returned as a sf spatial object.

The function was created following the approach taken in the stack overflow polygons from coordinates.
