R: A Semicircle Function

buffer_semicircle {buffeRs}

R Documentation

A Semicircle Function

Description

Creates a semicircular polygon, wrapper around buffer_wedge(point, radius, degree, degree_width = 45)

Usage

buffer_semicircle(point, radius, degree)

Arguments

`point`	Centre point of the buffer, must equal to true in: `sf::st_is(point, "POINT")`
`radius`	Radius of the buffer (numeric)
`degree`	The angle at which the wedge is centred (clockwise). Must be between 0 and 360 (numeric)

Value

An object of class sfc_POLYGON

Examples

example_point = sf::st_point(c(1,2))
example_point = sf::st_sfc(example_point)
example_point = sf::st_sf(example_point)

buffer_semicircle(example_point, 200, 90) -> semicircular_buffer
plot(semicircular_buffer)
