gs_random

Create a geom randomly

Description

This function creates a random geometry

Usage

gs_random(type = "point", window = NULL, vertices = NULL)

Arguments

type

[character(1)]
Either one of the three main feature types "point", "line" or "polygon", "random", or more specifically one of their subtypes, e.g. "hexagon" (subtypes currently not yet supported).
window

[data.frame(1)]
in case the reference window deviates from the bounding box [0, 1] (minimum and maximum values), specify this here.
vertices

[integerish(1)]
the number of vertices the geometry should have; only meaningful if type does not indicate the number of vertices already. If left at NULL the minimum number of vertices for the geom type, i.e. 1 for point, 2 for line and 3 for polygon.

Value

A geom.

Examples

# create a random polygon with five vertices
set.seed(1)
someGeom <- gs_random(type = "polygon", vertices = 5)
visualise(geom = someGeom)

# in case template is given, this serves as source for the window extent
visualise(geom = gs_random(), new = FALSE, linecol = "red")
